I remixed the UMP Hinge to include the K models receiver Plug so that you don’t need to use a picatinny attachment. I did this so there is not 2 failure points and it can just be slid into the rear of the K model’s receiver and then just attach the stock. It can be found on my Odysee.
Yippee Ki Yay UMP Brace remixed into a Stock to allow for a TPU Butt Pad and removed the strap guides. You can find on my Odysee
Only things you will need to change is your line width. I have finally tried a .6 nozzle for those of you asking if my settings will work for it. I set all of my line widths to .5 and I run the layer height at .12 or .15 depending on how detailed you want to get. That’s the only things you will need to change in my settings in order to get a great print with a .6 nozzle.
I am sorry and I hate to say this about someone else’s designs, but me and a few others on here have tried OKB 69 designs and none of them last or sounds great at all. I’m not trying to dog him, I’m just putting it out there before someone goes and wastes a stamp only to be disappointed. If you’re going to file the paperwork for one at least do a reinforced one.
