Dremel Adaptor M19x2 to 43mm

I designed a little Thing, which allows me to use a Dremel (or similar) on my Stepcraft 420.

I sliced it with kisSlicer and added NO Supports (for the thread).
0.1mm layerheight and relatively low speeds are required in order to get a usable thread.
20mm/s for Perimeters and sparse infill and 15mm/s for solid infill worked fine for me.
You should use a high fillrate (50% or something) to get a stable, durable Adapter.
