DL44 misc parts

This is some parts for the DL-44 blaster at https://www.thingiverse.com/thing:1915956. More specifically a grip screw head and the round silver thing on the side of the receiver (It makes it easier to paint).
I also changed the triggerMechanism to use 5mm rods as the plastic ones was breaking for me. I used some brass bearing tubes I had in my drawer. I also made some cutouts for the rubber band. Although a spring fits between hammer and switch.
I also added a switch holder for a 6mm mini switch that can be glued to one side of the main triggerMechanism part. (That way the mechanism can still be disassembled if the rubberband snaps).
The hammer is modified so it can hold a spring. Outer dimension of coil is around 5.5 mm. I printed the hammer with extra perimeters to make it stronger. The hammerMechanism is changed to a 3mm hole (as that is the diameter of the brass tube I had) as a printed pin could break from the force of the spring.
