I printed the Blaster and mechanical parts from PLA and need to use supports (in Cura i set Support Roof Density to 66.6%). I also recommend printing TPU rubber rings for shock absorption. Due to the force of the impact, it is also necessary to use a 3 mm x 50 mm wood screw to strengthen the launcher, because without the screw, in my case, the force of the impact broke it.
To assemble the Blaster you need:
- 4x M3x20 mm screw with countersunk head
- 1x M3x16 mm countersunk head screw
- 2x M3x6 mm screw with countersunk head
- 1x 3x50 mm screw (for wood)
- 1x pen spring
- 1x compression spring 1mm x 13.5mm x 80mm (I used this spring)
