Customizable (Dremel) Disc Shape Tool

thingiverse

I crafted this as a straightforward assistant for my Dremel drill press stand, to facilitate shaping discs from square stock. Start by selecting the material you wish to transform into a disc and mark its center and radius. Drill a hole in the center and attach it to the plug. I'm utilizing the same drill that created the central hole here, but feel free to use any tool that fits both holes seamlessly. Adjust your rotary device so that it just barely makes contact with the corners. Rotate your material, move the rotary tool further towards the material, and repeat this process until you achieve the desired radius. You may need to gently press the rotary tool into the material once it's rounded out but hasn't yet reached the optimal diameter. The customizable feature allows users to tailor the size of the inner hole, the plug's diameter, the support on top, and the height of both components. The attached STL file is an export of the default configuration, designed to accommodate a 2mm drill in the center. This design serves as a remix and simplification of one of my earlier creations, although that initial design also enabled cutting holes, which this iteration does not.
