Update June 8, 2022 - Huge thanks to Igsalas (https://www.printables.com/social/271394-lgsalas/about) for getting me the measurements I needed to complete this model.
I was asked to print a replacement knob for a Capresso Infinity coffee bean grinder. There are three different shaft sizes because I never had the grinder to measure anything and the broken knob I was given was in bad shape. If this helps you please let me know which knob fits the grinder best.
I do not wish to receive tips from any of the items I've designed or remixed. If I've made something useful to you and you would like to contribute a donation can be made to https://suicidepreventionlifeline.org/donate/. I miss my brother very much and it would mean a lot to me. If you are in crisis now there is help at 1-800-273-8255 or by dialing 988.
