I remixed this very useful design to fit my Power Craft dremel clone.
Unfortunately the original design doesn't fit as the threads were a little too coarse,
I have replaced the threads in my version using Tinkercad with an 18mm dia 1.5mm pitch thread that now fits mine and maybe some other Dremel clones.
If you're not sure it will fit, make a test piece. Either sink the print into the bed until only 5mm or so is actually visible in the print area and print that.Or flip the part upside down and cancel the print when you have 5mm, then test fit the piece. It will save you wasting filament.
