This is my second and hopefully simpler attempt at printing a roach clip. Both pieces are printed in PETG (should work in PLA as well, though I haven't tried), as positioned in the files with supports turned on for the overhanging features. I made the hole 4.5mm to fit the Raw filter cards I normally use, but it can accept larger roaches as well. It's simply operated by sliding the nub in and out to close the jaws around the roach. I added a loop at the end for a keychain or necklace. Overall dimensions are quite small at 56mm x 14mm x 7.50mm (except for the 2mm tall nub)
Please post your makes and let me know what you think, I'd love to see it!
Update: Made a slightly shorter (49mm long) model to get rid of some gaps
