The special thing about this Cap Shooter is that the cap will not only be translational but also rotatory accelerated.
This causes the cap to float like a frisbee.
Assuming all moving parts are printed with 100% infill made of PLA and there is no friciton, the cap will have a kinetic energy of about 0.4 Joule, a translational speed of 15.25 m/s (55 km/h / 34 mph) and a rotation frequency of 10400 rpm.

Supports are barely necesssary.

Most of the parts can be printed with low infill (I used 50% infill) but you should print the SLIDE.stl as solid as possible to increase its strength (I used 70% infill).
