I just built a 300% one A bit scared of tensioning it

So tempted to make this! This looks great! By the way it is "Five point three seven joules", not "Five point thirty seven joules".

amazing <3

Re-creating Da Vinci Catapult!

First off, this is an amazing design, an engineering feat. And thank you so much for providing it free to everyone. I was unsure about how to print the springs, so I did concentric with 30% infill, so it resembled a leaf spring on the inside. I don't see it mentioned, but from the short printing video it looks like you made them completely solid from PLA? I thought they would break like that. Thinking about also trying TPU. Looking to maximize the energy of the springs for further throws!

You should build more gravitrax parts

Where can I get one?

this is dangeours. why is youtube allowing creators to post videos of 3d printed assault weapons?

found it on thingvers Works great thanks

One very important thing is to remember to have the arms in the back pointing upwards and the arms in the front point downwards before you assemble them onto the base frame. Otherwise they're be in the wrong position and you won't be able to rotate them in the correction position since the frame will be in the way. Also remember to have the joints facing in the upper left hand corner to the lower right hand corner otherwise the thing won't fling correctly. It's a bit hard to describe but that's what I've got for now.

Finally, a useful 3d printed object.

This is seriously the coolest thing I've ever printed! Now I need to print enough for a fun siege

i printed this but it's not "snapping" like yours. like the blade isn't catching tight enough. Any suggestions? Thanks so much!

This is an absolutely awesome catapult. And it has alot of power for such a small device. Significant improvement over the rubber band powered ones we've all played with in the past. Could those leave springs be utilized in a crossbow or ballista style weapon as well?

This was so cool. I actually printed 3 of them. One at 100% one at 50% and one at 190% which is the biggest my k1c can handle. All three work incredibly well. I printed it all in pla except for the springs. 25% infil on everything except for the arm which i printed with 50%. For the leaf springs and stop i printed them in petg with no infil but like 20 wall loops (enough so they were solid wall)

works great, Now I can play with 155 in the field and a 200% version of this catapult in the office 🙂

Printed great on my 2 modded Klipper Creality printers. Great design!

Someone modeled a cover for the spring area so that it’s easier to use, and it is probably a good model, haven’t gotten to print it though. Planning to print today or tomorrow

Printed it in my P1S. Man this thing is serious! I am making my second now to vs my daughter in cup challenge. Some recommendations. Holes or something to place in ground maybe streak holds or something we can print and attach. Also the video was amazing great detail love it. The assembly was a little fast and when you move your hand in front of the model I cannot see it. Besides that I just got this printer 3 days ago and it's wild I can print amazing things like this!! Thank YOU!

Great design. Printed at 125% and wow does it have some power for just a toy

I have a problem. In my case 4 lower springs breaks or have ti much power :/ grown man must use both hands to push it back and in 3rd time it brokes

This video is useless to me

Back then...probably even now you can find a rubber band version of this at one of the festival stands. The bolt had a smaller head on it and was pretty accurate.

The moment i walked in the kitched the fly that was pestering us never came back before i could try it out...

I am going to go harass some bobbies with this and try to get arrested.

Hey if you could can you tell me how much filament the 210% catapult was

Just printed this thing out, such a simple design that I’m going to be playing with for hours on end 🎉

I have printed multiple of these already and they work fantastic. I would love to see an option, though to cover a spring as my hand gets caught and then it won’t work

This is def in my top 3 coolest functional prints of all time. My son and I love it and I cannot wait to try to print the 210%. I wish i had the talent to design stuff like this, i just know how to print it!

Very cool!

I'm currently almost finished a 275% scale print of your catapult in CF PETG and TPU. I let you know if my catapultmaxxing works out. 😁

This thing would be insane if printed on that huge elegoo printer. wouldn't be surprised if it goes over 200 meters or further at that size

Made it, needed to reduce the width of Stopper by 0.5mm in my Qidi Q1 pro. Great Model.

Was quite a waste of material. Broke on the first try.

My favorite part is when he spazzed out and did it really fast.

I love how most of your projects just use 3d printed parts instead of extra parts you have to buy like screws

Bro created a compound bow 😂 then Dry fires it for education and tests at an archery range. Hahaha

it would be nice to list the actual settings for those that don't use bambu studio. cool design otherwise

We need this for Wolverines claws 😳

this is break my brain

I printed this for the mosquitos and now they are missing lol.

Yaptım ve çok güzel çalışıyor

You just assume anybody uses a noob bambu printer :D. But nice project. I like it very much.

Always lube your annulus....

Oi mate, do yar have a loicense for that knife?

This is awesome, thank you for not only making this model but also making a high quality video explaining how it works and how to assemble it

"It's not sharp" Won't stop people from complaining about a toy.
