About this 3D model
I purchased a Dremel chainsaw sharpening attachment: https://www.amazon.com/gp/product/B003BIFMK6/ but it did not fit my Ryobi P460 rotary tool: https://www.amazon.com/Ryobi-Variable-Speed-Rotary-Packaged/dp/B07NVQMP78/ so I designed this adapter (which was quite easy using the thread library). I would recommend something like PETG, ABS, ASA, etc. PLA might be a bit too weak to stand up to much abuse.
