Card Launching Sewaddle

This was printed on the Snapmaker U1, it takes full coverage of the bed and 4 colors. I would recommend a print bed of 270x270x270 or more.  

You'll need some foam (3/8"W, 3/16"T), micro cord, rubberbands, and a M4 65mm screw

You'll want to use the microcord to tie off the launch piece. 

Then prepare the rubber band posts by applying foam to the 4 body and launch rubber band posts.  This adds cushioning so that the posts dont break on impact.  You don't have to add the blue rubber band in the picture.  The M2.5 screw for the body posts are also optional.  Use a rubber band that can be doubled over to tie the body and launch posts together.  I used one big one that got double looped

For the trigger, put in the button, then slide in the trigger and use a small rubberband to secure it to the upper half of the main body

Join the two body halves together via the dovetail joints and secure it all together with the M4 screw that goes through both body halves and the trigger.  

Note: these can shoot with a lot of power depending on the rubberband.  If the posts breaks, epoxy can do a great repair, then change to a weaker rubberband and add more foam
