Bolt Action Pen (Pilot G2 Conversion)

Conversion of Pilot G2 to a bolt action pen. This model retains the original front end that is sleek and comfortable. To Assemble:Take the black cap off of the ink cartridgePlace the Bolt into the 3D printed topScrew the grip of the pen (with the spring and ink cartridge and make sure the bolt goes inside the end of the ink cartridge) Please give me any feedback and I will make improvements. This is my first model and I have a lot to learn.
