Oh my God, Electric cars, restaurant reviews, south of France and now 3d Printing this channel just gets better and better. Well done Lads keep up the great work 👍
@@MeandMonAmi hi, i have been following your channel,. because my sister want small electric car, and you give most videos about it. I found best thing about this car, is being charged by regular 220V cable.
Really enjoy your videos....have you thought of printing something to keep your door open while doing pieces to camera?....probably better than the cardboard box....
You two are brilliant and such a great idea for a channel. Wouldn't matter if you changed the car or added another and went further afield! Those of us in grey old England tune in especially for the weather... Thanks..
That was absolutely amazing! Thanks! And if you can design something to keep Elton's door open while you're making a video, you'll be home and dry . . . Thanks again! 🤗
Please - - I have no room for one of these and for years I have convinced myself that I don't need one, but if you keep showing all this neat stuff you are making I may not be able to resist much longer. Fortunately I am not sure I need to learn yet another piece of software in-order to design all the little gizmos I would like to have. Another great video.
Wow that’s brilliant, never have understood this 3D printing malarkey….until now. But there’s no stopping you now Tim. How about a new body shell for Elton made out of that soft plastic so he won’t get damaged in those narrow little lanes 😆
You have managed the art of video editing to near perfection, and with time you will become a 3D printer artist. From your video - what about a mon ami door distancer? Just a distance block, perhaps with more than one measure that can hold the door open like the cardboard box you used in the video? Or from some past videos - a gimmick to hold the window open in various angles so that it isn't always binary, open or closed?
Brilliant adventure Tim, thanks for sharing! Quite remarkable results. As mentioned, I do some work in Solidworks and available to assist with designs.
The Citroen Ami community has published a lot of 3D files for various replacement parts/accessories/enhancements. And please DO NOT USE PLA. This plastic will melt under the sun. There are better plastics for making car parts that can withstand the heat and the UV rays from the sun. Keep up your excellent work. Also, about plastics. If you use PLA it is biodegradable (mostly)
@@MeandMonAmi given the quality of your printer, an enclosed one, you could use ABS. It's a tricky material, as tricky as TPU. But as you've already been successful with TPU, ABS should be a treat. The reason for choosing it is just the higher temperature it can endure. PLA will soften and loose mechanical strength much easier. By the way, I'm a neighbour, on the other side of your hill, not very far !
You shouldn't have to justify your 3D printing hobby. Welcome to the RepRap club. Just one word of advice, don't rely on being able to leave the printer unattended. Even for PLA filament you are dealing with high temperatures. If you have home surveillance available, point a camera at the printer when you go out. Happy printing!
How exciting. When can we buy a key ring? I wanted to try 3D printing a few years ago when it first appeared in the crafting world. Now I am going to investigate more - and perhaps add it to my Christmas List 😀
Ha available in all good stores!; if people want some I could put them on the Meandmonami website. I’m really enjoying it. It uses a different bit of the old Brain box
That looks like great fun - I am extremely tempted! You might be able to design a semi rigid device to replace the milk (?) carton holding the ami door open and put it on thingiverse 😀
This is inspiring me to go for a basic Ami and to ‘print the good bits’! (Bag hook etc). It seems that the collective hours put in by amateur 3D print designers may be able to overcome some of the foibles and short-cuts taken at the factory, so we all end up with an Ami+!
What a great video. I've often thought about getting a 3D printer, but had no real ideas about how I would use it. Your trials show how useful such a beast can be. I certainly wouldn't worry about plastic waste, our local authority incinerates general waste to generate electricity, so no problem. Thanks for this, I'm enthused.
Next project for your 3D printer adventure - tiny bolt that could press in the flap of a charger station! Better than having Mr. Boo standing in the parking park ant sticking his finger in the door for 1.5 hours...
I was wondering when you end up with 3D printed parts. Great job on getting that filament change for separate final layer colors, something that many decide to leave out on their first prints.
It shouldn't get any crazier, will you become a mon ami 3D print master? Such a printer seems very nice to me, but once you have printed a few things, I fear that you will be done with it very quickly. But I wish you a lot of fun with it!
Hi Tim from Spain. GREAT! There's no other word for it. I have often wondered about a 3D printer but I know that 'er indoors wouldn't want me to have one alongside all the other things I've bought in the past and hardly ever use so I am vicariously enjoying your efforts. Thanks Tim, that was very informative.
Hi, I got a 3d printer a few years ago when I was designing something specific and it's been great. Even designed and printed a replacement part for my mum's shower door that was no longer made. Of course I've also done loads of things from thingiverse as well. It is fascinating seeing something come into being after just being on a screen. The advantage is if the thing breaks - which of course will happen, it's pennies to replace. Interested to see what other uses you find for it.
3D printing is amazing, you can create you own accessories, several shapes and materials for daily use or just for fun. I guess as the time goes on more and more files will be available all over the internet, however you may need to test the materials resistance and melting under scorching heat, in some places like the south of France a car parked in the sun can rise up inside well above 60ºC, I hope the materials last.
I've always fancied getting a 3d printer, but have never splashed the cash. Maybe I'll look into 3d printers again. A good idea for a key ring is to 3d print small figures of yourself and mr boo, similar in style to the keyrings that funko pop ones.......they would definitely then be exclusive.
Mister Me and Mister Boo...well i never..or maybe i did😂😂 I've got to confess you lost me after about 20 secs of explaining how it all works 🤔 😂😂😂 But i have to say bloody well done Tim on producing the goods 👍 🎉 they look really good 😊 now where is this leading..?? Is it possible to clone Mister Boo..🤔🤔🤔🤔 would it be a ' style icon' 🤔or is their only ever gooling to be just the one ?????? 😂 fair play to ya for getting to grips with this technology i can only admire from a distance 👏 🙌 remember to stay well & of course mote important stay charged 💯👌
Bravo! More fuel ⛽️ to your fire 🔥, you should be able to use recycled plastic for 3D printing. Anybody against 3D printing hasn't smelt the coffee yet
If Citroen makes it's parts copyright free, it would fit nicely with it's Eco-Friendly ethos of the Ami if you could built your own spare parts reducing your carbon footprint by avoiding ordering original parts online or from their dealers.
@@MeandMonAmi I imagine if they start off with the small parts like the orange parts and wing mirror covers for example, things that can be produced on 3D printer like yours, would be a good start. Perhaps in the future when industrial car 3D printing becomes more affordable and practical for them, then we may see it becoming mainstream in the same way as EV vehicles have become so in the past decade. Could you contact Citroen and see if they would be interested in the concept and you and Mr. Boo could produce a video of the interview either in person or via video conferencing?
Hi ! I hope you didn’t print the elements for the car with PLA. Because it won’t withstand the heat. It will melt and deform. It is preferable to use PTEG filament or even better nylon filament (difficult to print but very heat resistant and very solid) ;-)
well you make fun videos ,am from scotland ,any way i saw the concept idea they had like year ago ,now website has divfferent one coming to uk ,soon ,anway the concept had some great stuff but shame not all is on new buggy but with ami with roof rack ,well could do some 3d printing roof rack parts also ,in buggy one the door is different so could infact make door panels me be ..........but its shame the buugy concept dident make as could add few intresing stuff i loved that full beem head lights too spare roof tire and well plastic window slash door could make 3d printed frame and as low door there had carry away bag so with the new buggy could still add own inand outer bag or box concept making more small space ..with buugy typ roll cage me be have to be cliver but could be fun ...........
A Ami based guitar case or carrier mounting brackets/clips. A removeable dinner tray arrangment/mobile office desk/mobile music studio editing desk. Speaker mounts, and a dash mod that you can attach a LoRa type radio device for about 25 bux, that can allow for free 2 way email access as that can allow for ordering a pizza while from the middle of rural nowhere to be ready for pickup, also allowing for a best solution in areas that have no cellphone coverage even if should the batteries run out of power and your stuck and dont want to fully expire from frostbite because that really never produces afterlives, even if putin in the big club carlin mentioned about, says otherwi$e.
I cant buy from Amazon because of the packaging. I bought a watch strap , the courier tried to deliver it 3 times. I was puzzled because it should easily fit through my letter box. I had to arrange to pick it up at a shop. the box was the size of a shoe box. It costs power to recycle . At the time he was the richest man in the world and he could not care less about the world .
Just don't buy those seemingly very affordable memory cards on amazon even if they have good reviews, because bezos lacks the meaningful integrity enough to want to sweep his multi billion dollar cash venue free of any such enabled fraudulent problematic concerns. He could hire someone to do that, but maybe sweeping the deck of the fancy new boat seems more distracting of him. I really don't think he's atheist, based on performance. His twitter was hacked by a saudi billionaire in 2018, by the same saudi billionaire involved in the 9/11 thing, and the same saudi billionaire that threatened to pull a 9/11 on toronto's cn tower, that deleted the twitter post 15 minutes later as the mainstream media went about shoving the ordeal under a very prophetable rug as is what they tend to do.. Ok, back the Ami.
My advice is don't tell anyone you are 3D printing they will pop by and start by saying things like, "Is it possible to 3D print a door wedge for an Ami so when you are filming it keeps the door open?". And you say yes I could that for you ... They then say, " Can you do 50 of them?" PS the door wedge was just an illustration as 50 of them would be ridiculous. But I guess you get the idea.

This is a great thing to do Tim! Really look forward to seeing what you can create! And the colours too! You can truly customise Elton now!
Indeed should be fun!
