3D-printable Davinci catapult gift card

- Because a lot of people liked my previous gift card (Fully 3D-printable wind-up car gift card: www.thingivers...) and asked if I could create another version of it, I decided to make this Leonardo Davinci inspired catapult gift card. The whole card can be 3D-printed in one go, you don't need any extra parts except for some wire. The card can be printed without support and the print time is about 3 hours with a 0.2mm layer height. The card can be printed using regular PLA. The whole thing is designed to be able to snap fit together so there's no glue necessary. I did a lot of test prints of different parts of the model until I got some consistent and good results. It is of course possible that depending on which printer you use the result may vary. You can always let me know in the comments which parts work for you and which don't so I can create a second version of the model. I added all the parts seperately to for the people who just want to print the catapult and do not have the intend to give the card as a present.
All slow-motion shots are filmed at 240fps with an Iphone 8.

Happy 3D-printing!
If you're wondering how I do what I do and how you can get started creating your own prototypes I wrote a basic guide about it.

Recently found your turntable design, and it’s clear, you sir are a stallion among mules. Aim high my friend
Thank you very much man, appreciated 😁👍
Damn what a beastly comment 🙏🙏
How do i string it ?
This thing I found else where, just saw this video - Printed it - this has some punch
Best example of 3d printing ever, and very nice work.
Thanks man 😁👍
I think its awesome! great model
Magnifique travail. Merci !
Very good job. Thanks!
It's an awersome thing!
Is it possible that you could make a version with looser tolerances?
Can one effectively print this with SLA resin too?
i am too dump to allign the string, so that it pulls even on both sides, please help!!!
how far does it go
Thanks dude.., But, is there any trick from assembly design to multiple bodies for printing 1:01 ? I did some search without any luck.
Hello Angga, There's no real trick to it. First you design your model and then you arrange all the individual parts flat on the grid manually with the move command and then you draw runners between all the parts to connect them like in a model kit.
None of the pieces fit together for me
That means your printer isn't configured correctly
How many walls did you use? I used 4 and its to thick
Hello Steven, I use 2 walls.

Just to answer some frequently asked questions:
-The 3D design CAD software used in the video is Autodesk fusion 360, which is free for students and startups.
-There's a complete step by step manual available for this catapult gift card, you can find it on thingiverse and on hackaday.io, links are in the description.
-Links to the STL-files and instructions are in the video description.
Is there a trick to getting the release lever into the holder (number 7 in the instructions)? I've broken 3 of the holder tabs trying to put it together and the video cuts to it being installed already. :)
I’m aware of the issue and I’m working on an updated version but currently all my projects are on hold because I have exams.
@@BrianBrocken Sweet! Good luck on exams and I look forward to an updated version. 😁
Thank you Dana! 😁👍
Thank you for your hard work! I printed one of these for my little brother doing a school assignment on catapults.
Hahaha awesome man, glad it was usefull to your brother ;-)
Very cool! 😎 Thanks!
I got this as a gift. My only real problem is figuring out how to wind the string. Even when I watch the video at 0.25 X speed, it's too fast to see how to do it. I'll take a look on thingiverse. Still very fun!
Thanks for the relaxing music during the rope winding part.
Just built this one tonight. Works great 😆👍 I will put a video up on my channel on 3rd of February (obviously with credits to your design).
Haha thanks man that's great ;-) (thanks for the sub btw 😁👍)
Thanks for the awesome designs! Amazing work!
Thanks man 😁👍
Thanks for the video and the model. Great music choice!
Thanks man ;-)
Danke, gute Arbeit
Awesome but can you upload some details about how the windings should be made in the axle?
I uploaded a complete manual in pdf format on thingiverse you can find the info in there.
thank you friend, my son loves it
Can this be scaled up?
Cool print man! I can't wait to try it out and give one to my niece. Thanks!
¡Genial!
I had to resize a number of parts to make them fit, so no trimming and sanding. I can now give them to my grand kids and don't drive the parents crazy. On the trigger-beam. There are two things to look for. First - on the cross support trim any over hang the might interfere with the arm. Second - if your slicer is set for brim. make sure to remove any over hang from the brim. This correct the problem for me.
