The file 'Experimental Gel Blaster Hop-up 3D Printer Model' is (skp,stl) file type, size is 1.7MB.
An old attempt at trying to make a Hop-up for a Gel Blaster. The design was never finished, but is being uploaded on request from someone who wants to try their hand at it and build off my work.
Variants provided in the STL include a straight flute and 0.25mm rise with both an 8mm and 7.5mm ID.
Suit a 9.5mm OD barrel. Supports are required due to the 90° internal lip.
The SKP file (SketchUP Make 2017 or newer required) includes other variations which have not been exported. These are included only for posterity as they proved ineffective, at least in my testing. Said variants include a "bump" style insert card (to see if different levels of interference helped), and two different "riffling" attempts.
