Dremel TIG Tungsten Grinder

I used the Fusion models from the original poster to re-scale the base, increasing everything but the Dremel attachment threads to 1.1x size, for compatibility with the 38mm diamond Dremel wheel common in the United States. I've also attached a 1.1x scale STL of the head, which is otherwise unmodified.

The fit isn't perfect, but pretty good. The inner hole needed to be expanded a bit for compatibility with the EZ change Dremel mandrel, but shouldn't need modification for a normal mandrel. 

Some silicone on the base-to-head threads goes a long way towards preventing binding.

Recommended print settings:

• 0.16mm layer height
• 5 perimeters
• 5 top and bottom layers
• 40% infill

All credit to the original designer, this is a fantastic design, and the only one I could find that correctly orients the grind marks parallel to the tungsten rod.

Update - Apr 28 2024: I often use this grinder without a collet as a heat sink, but the original PETG filament I used didn't hold up well over time to the heat. I reprinted the head in CF Nylon for heat resistance and rigidity and it is working much better.
