Hi, thanks for the video! Will has offered quite a few great projects! I built this mech the day it came out. I have since "mixed and matched, several of Will's eye mech into a hybrid design. I found a nice little trick to make the snap fitting quite a bit easier: Use a small amount of heat. It gives just enough give to allow for and easy fit. But, do not overheat the joint as it will become molten quite easily.
When I fixed the original build no, as I was still waiting to build the controller, which had different wiring to my original one. Later I powered up the board with the arduino attached but the servo 'horns' not connected, which should have centered them. Works great now.
Thanks for the video! I printed some parts and the assembly (snap fit) goes relative smoothly, but once the parts are together, the "friction" is high, making movement very difficult. As a result, the servo doesn't generate enough force to move the components effectively. Do you have any suggestions or advice on how to reduce the friction? Thanks!
Maybe try a bit of Lithium grease? The white stuff they use on ball bearings on the bike. Tell Me did you use ABS? Will said in his video that abs was tougher but a bit more grippy IIRC. Maybe just use a drill bit and hand turn it inside some of the hole to give a bit less tolerance You might break the parts trying to get them apart so maybe do some test prints and see if youcan improve the movement of the joints by gently reaming out the inside of the holes with the correct size drill?
Great video! I've been trying to print this mechanism this week, but I've had real trouble getting the tolerances to work, none of my pieces snapped together as nicely as yours did or some of them at all. Would you mind saying what print settings/hardware you used?
I’m actually planning a follow up to this as I printed the eyelids vertically which caused a lot of my issues with the joints breaking so I need to blame SpiderMaf and not imply it was Will (in case it sounded that way). I printed these on my Bambu p1s and the settings were just the standard settings for the Bambu pla matte filament I was using. So nothing special at all. If you want the specific settings I can load it all in again and check for you.
@@spidermaf The video sounds great! I'm using an Elegoo Neptune 3, it's hard to know if it's an issue with how I'm printing it, or if the printer just isn't up to snuff.
The base is just less than 14cm×10cm and with all the parts in its approx 6.5 cm high, although might go a little higher than that depending on the position of the up down servo linkage
Will added the gerber file (for the board) as well as a bill of materials in his download pack. Also have a look at my video about ordering the parts and the board - It might help if youve never done it before. My videos at: th-cam.com/video/NRquXVQcvig/w-d-xo.htmlsi=1e5mjCNcpS-bz4Ju
@@spidermaf when I added them to cura, they show as printed on the pointed end - Will prints them facedown - which makes sense, I will try supports but i think he also said he didn’t use supports - the beige looks good, idk if I will use a whole roll tho
@recom273 I'll have a go later as I want to be printing some more out anyways. (Its addictive. )The way I did it left some artefacts on the side of the lid which show in my video as well so that might solve it. Mine I literally just printed everything straight out of the download pack. Thanks for spotting that @recom273
I think that nailed it. I printed with the blocky parts on the bed, which means the shear points of those side rods are now along their length, not across their width like when I printed them on their end. It's now way less fragile.. Well done for spotting that @recom273
@@spidermaf I gave up on ABS because it shrinks too much, and not in a consistent fashion. PLA has great accuracy but can be so damned brittle as you're finding.
@@spidermaf Yes, I've seen them. Can I DM you? I'm creating a puppetry service for children's hospitals, we'd love to use his eye mech files, but cannot 3D print. If you're interested in helping, I'd love to talk.
I have to stop watching your channel because it makes me want to buy a 3D printer every time. Which means buying a computer to get the files. Cool build and yes you need to either build a control until or make an app for your phone

cool build - did you have to "center" your servos before assembly?
When I fixed the original build no, as I was still waiting to build the controller, which had different wiring to my original one. Later I powered up the board with the arduino attached but the servo 'horns' not connected, which should have centered them. Works great now.
Hmmmm...I may need to look into this for a recent project. THANKS FOR THE VID!
You should. Super fun project.

Great video! Do you know the dimensions? It would be extremely helpful to us before printing, and the original designer hasn’t let us know!

How do I order a premade board? I have no idea what parts to order if building one myself, I am ok with soldering but not familiar with all the parts

Did you print the lids with support? I saw Will prints them flat side on the bed.
I printed them in the orientation they were supplied using organic supports.
@@spidermaf when I added them to cura, they show as printed on the pointed end - Will prints them facedown - which makes sense, I will try supports but i think he also said he didn’t use supports - the beige looks good, idk if I will use a whole roll tho

👀 AHHHH! WHAT A COOL VIDEO! 👁 👁
They are watching you 👀
Perhaps you need to think about using a PLA+ filament, they tend to be less likely to break.
Yeah, or abs. I'll try and get gold of some pla+ and see how it goes.

Where can i find the stl file plz great vid ,.//.,
Thanks. All the links to the eyemech files are in the description. Stls are in the main download pack.
That's a really well designed project, thanks for showing it!
Can I buy the kit at the beginning of the video?
Will Cogley has shared the stl files for free so you can download them and print then yourself.

@@spidermaf If I could, obviously I would. If you don't want to help a children's charity, that's just fine.
@@darrenkairis9733 At least here the library has a 3D printer, costs very little

I'd just be happy if they looked at anyone who entered the cave... or maybe I should build them into a furby
