Finally a solution that works with the Hydra mod AND doesn't fall off!! Printed mine in PLA mainly because I couldn't be bothered to dry a roll of ABS only to find out these weren't going to work like many others I've tried. If/when these break, I'll drag out that ABS and dry it so I can print new ones. Thanks!

These look and fit great all without using much filament. Unfortunately, they don't work with the Hydra mod, but that's my fault for not reading. Wish I could use these!
