Replacement bushing - GSI Outdoors JAVAMILL manual grinder

thingiverse

This replacement bushing is specifically designed for GSI Outdoors' JAVAMILL portable manual coffee grinder. RSI markets these grinders to outdoor enthusiasts and travelers, who use them to brew coffee while camping or traveling. This bushing fits snugly between the rotating ceramic mill and the drive shaft. I've discovered that this bushing's internal design allows for excessive play, which can cause it to deform under high stress during fine grinding, even at espresso level. To overcome these limitations, I've created a replacement bushing. The fit is precise, thanks to printing with PETG on my Monoprice Mini Select 3D.
