Tactical Ballpoint Pen for Pilot G2 Refill with possibility of Metal Clip

This model is based on an normal version (2 wall layers) of a Tactical Ballpoint Pen https://www.printables.com/model/412788-tactical-ballpoint-pen. I adjusted it for use with Pilot G2 refill. I also added a small protrusion, to which you can attach a clip from a piece of wire.

Print Instructions

I printed  it with 0.2mm layer height, with organic support inside the pen (see the 3mf files). Print any material you would like. I printed it with PETG.

Assembly Instructions

Print one pen and one endpiece. You'll additionally need an M3x10mm screw for the handle to screw in the side of the end piece. Set it together with a Pilot G2 refill and spring. I used slightly wider spring (6 mm diameter, cca 16 mm length).

For more precise writing control, you can heat the tip of the pen and adjust the diameter of the hole around the cartridge for a tighter fit.
