Works perfectly with 3d prints and brass. Haven't tested on anything else. Fits taps from M3 to M8. Larger sizes will probably work though likely not smaller ones.
Parts required: -1 x M5 x 20 mm -1 x allen key/screwdriver
For the body, I printed the prototypes at 20% infill, 4 walls/tops/bottoms and they were unbreakable. The final version that I will be keeping was printed at 100% infill; it was only a couple of grams heavier and took 10 minutes longer to print. Takes about 55 minutes to print at 50mm/s. No supports. The hole is threaded but it might be a hard to screw in the bolt the first time.
For the pinch block, print it at 100% infill pointing up (like in the picture) with no supports. Print a few of them because they will eventually wear out I imagine.
Please post a make and like if you found this print useful. Thanks!
