About this model

Similar to 5C collets, but not exact, as I do not own one; the purpose is to hold the end mill to be able to sharpen it manually, I printed using Creality 3v3 upright; no support required, only brims I used. More sizes on request. To hold in place, a 12mm 1.75 bolt can be used but is not required, as the fit is tight. I lightly sanded just to smooth the edges; it works for me. Hopefully it will do for you. Also included on the models is the block stopper to control the amount of material to be removed equally. The purpose of this design was to be able to manually sharpen the end mill. The bolt and nut are a bit tight, making it hard to turn and preventing backclash. The SHolder need support as I printed upright all of them.
