This is my take on a crimp strength trainer. I have big hands and it allows for 2 or 3 fingers - smaller hands might get 4 in there.
I have provided 4 sizes that I thought work well for my needs: a 15mm open and 12mm, 15mm, 20mm closed backs.
These are designed for use with a 6mm rope, but should work fine with smaller. Just note that a smaller rope will apply a more contentrated force on the print. I made a loop and fed it through. This lets me easily choke weight plates or a pull-up bar.
Printing:
Print on it's back. I recommend ASA/ABS (maybe PETG) with 7 walls and 25-50% infill. Layer height and top/bottom layers don't matter too much with these settings. Check the slice preview to ensure there's no gaps between the edges (see screenshot).
I printed the open back in ASA with 7 walls (grey model). It's super strong. I haven't hung my entire weight on it yet (mainly as I can't hold that) but I'm sure it'd be OK.
The other 3 are all in PLA with 5-7 walls. They all seem adequately strong but not as strong as the ASA.
Safety:
I've tested these with up to 20kg of weight and they seem fine but I can't guarantee the strength of yours - it depends a lot on how you print it. I recommend testing them before loading with to much meight. You really don't want plastic bits stuck in your finger.
