fully printed compound crossbow

thingiverse

Reliably fires 4 inch groups at 15 feet. Functions exactly as you would expect a compound crossbow to function. Bolts are designed so they spin in the air for accuracy. The only non printed part is the string. Most things can be printed at low (10-20%) infill. Many parts work at .2 layer height, but print the small items and the bolts at .1 since they require high resolution to work properly. Bolts should be at 100% infill so that they have good nose weight. Print them standing up so they are properly balanced. Use the stl with included supports if the bolt tends to wobble during the print. Printing with a brim should also help keep the bolt stable during the print Bow does not seem to have noticeable wear over time. Trigger spring is still finicky |     || |-------|----| |2x |body.pin| |2x |bow.pin| |1x |bow| |2x |cam| |4x |clip| |1x |frame| |1x |grip| |1x |grip.pin| |1x |hook| |1x |trigger| The string is the only piece not 3d printed.
