The file 'Coffee Bit Adapter For Hand Grinder 3D Printer Model' is (step,stl) file type, size is 406.5KB.
After realizing how long it takes to hand grind coffee and printing/breaking several of the existing hexagon to pentagon adapters, I remodeled this adapter to use a cordless screwdriver with the Javapresse manual coffee grinder. This adapts the hex socket to a pentagon socket and also spares me from needing to buy another kitchen appliance :)
Print horizontally to avoid vertical delamination. I use 100% infill, support angle at 60 degrees, and support density 20%.
Stronger materials can be used, but this has been working (so far) in a modified PLA++ from Breathe-3DP that I recieved in a MakerBox sample.
