This is an updated/improved version of this model: https://thangs.com/designer/calvinm/3d-model/Cafelat%20Robot%20Basked%20Grinder%20Adapter-32182?manualModelView=true&source=mymodels

It now prints in 2 pieces which allows printing without supports and eliminates the error-prone parts of the older model.

The threads might require a bit of breaking in to go smoothly. Rubbing an unscented candle against the threads works perfectly for a lubricant.

Please forgive my poor print quality in photos.
