Mounting bracket for E61 Espresso portafilter / group handles.
There is room at the back to snap-fit a 25mm / 3mm magnet, and a circular groove to fill with silicone to reduce slipperiness.
Inspired by, thing:643645 . But that design was just too brutalist for my liking.
Recommended printing: 2 shells, 30% fill.
After printing insert the magnet into the cavity and spread silicone over the rear of the mount. This will ensure that the mount doesn't slide and has a nice grippy high static friction coefficient.
Made with OpenSCAD.
