Yet another hex bit holder with one key difference.
It has 3 different fit tolerances and a size tester to help you pick the perfect fit for your printers tolerance.
See the reference below.
Please note that the tester seems to print marginally smaller slots than those in the block. Not sure why but if a secure fit is needed consider going tighter than the tester suggests as you can always file it down afterwards.
Comes in 1x1 and 2x1 sizes, both with magnet holes.
An f3d file if you need a different size or set up.
