Dremel 300 Series Direct Mount

thingiverse

I am currently working on a project and have some notes. The design is slightly too large, coming in about 5mm shy of its intended size, which causes it to interfere with the X carriage bearing mounts. The Dremel I'm using is also quite oversized for the HyperCube's 8mm aluminum rod, making it somewhat cumbersome to maneuver. Nevertheless, it does manage to produce parts, albeit those with intricate geometries tend to be inaccurate, often deviating by more than 5mm from their intended specifications. This discrepancy could be attributed to a multitude of factors. A test square, however, revealed an impressive level of precision, with errors not exceeding +/- 0.25mm, which is remarkable given the amount of flexibility involved. I recently created a design in Fusion 360 that allows for direct mounting of a Dremel 300 Series toolhead onto the HyperCube machine, thanks to Chris's ingenious work on modifying the HyperCube into more than just a 3D printer. The dimensions were derived from a Model 300 Dremel with an AU plug. My design is still under testing but has shown promising results so far. When complete, I'll be sure to update this post with the final outcome. One thing to note is that the part cooling fan was too aggressive and caused issues with warping. I plan on also designing a version for the Model 225 Flex-shaft unless someone beats me to it.
