HK18 (M4A1) Gel Blaster Stock Insert

thingiverse

So recently bought a Gel Blaster (https://m4a1gelblaster.com/products/mk18progoldblaster) and been having a lot of fun with it. One thing bothered me however. This is a beautifully designed replica, very nice attention to detail, and then there is the stock. You can see the manufactured strengtheners and it has holes in it. I guess an attachment is designed to go here but without it, it just looks unfinished. 3D printing to the rescue! This insert just clips tightly onto the stock covering the ugliness. It's held on by pressure, retainers and by being wedged under the stock adjustment latch, so it should never fall off. Install is easy, easier if you have one of those "shatter proof" school rulers.
