This is a remix of another design in which I added slopes to 90° edges to improve strength, added bolt recesses for better functionality, added measurement marks, and did some overall trimming to reduce material that did not contribute to strength. I printed this in true silver Hatchbox PLA. I personally have a Dremel 4000, but from what I have read, this will work on any Dremel with the same threading.
I would say a raft is essential to prevent lifting.
The 1/4″ nut will fit in TIGHT. Might have something to do with the PLA shrinkage, but either way it means the nut stays in the knurled knob (which is a good thing in my opinion). Just tap it in with a mallet; works like a charm.

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
