The Hand Cannon is one of Fortnite's most iconic weapons! This real life prop replica has realistic blowback that allows it to chamber and eject empty cartridges!

Notes:

Print Mag_Left and Mag_Right at 0.3mm layer height if possible. If you print at 0.2mm, an extra layer will be added and it may not fit properly in the mag well since it will be slightly over sized. I was able to get consistent results at 0.3mm layer heights and saved some printing time!

Post-Printing

SAND ALL CONTACT SURFACES!

If you want your Hand Cannon to function like shown in the video, you need to sand all high friction areas, including but not limited to the Latch, Launcher, Frame and Bolt. Use a doubling strategy from 100-200-400-800 grit sand paper for best results.

Watch the video first before starting assembly so you can familiarize yourself with the process and do it right the first time!

How I Designed This

I Use OnShape for All of My Designs

Everything in this project was based on the following collection of videos I found on YouTube pertaining to both real semi-automatic firearms and hand made rubber band guns.

Here is a link to the public OnShape file where you can copy, view and edit the parts I designed for yourself.
