20ml / 20cc syringe gun

thingiverse

The original gun was created with a codan 20cc syringe from RS Components, article number 768-2328, used as a makeshift glue dispenser. Printing instructions follow: There is no raft required for this design. The infill density has been set at 40%. Three shells have been programmed. The layer height will be 0.2 millimeters. A special note: The parts pusher, plunger and trigger mechanism do not require supports. However, I would like to suggest that you print the magazine on its side for added structural integrity. Specifically, this means making sure the through hole axis is parallel to the Z-printer axis. Here's a breakdown of the materials needed: 1 x compression spring with L0=32mm, Di=6.7mm and 0.61mm thread *A longer spring might be even better, try 37mm* 2 x screws M3x25mm (use one as replacement for rod Dia 3) 1 x rod Dia 3mm, L50mm 1 x compression spring with L0=16mm, Di=3.7mm and 0.4mm thread 1 x screw M3x15 1 x rod Dia 2.5mm, L10mm
