58mm Portafilter Holder for Turin SD40

58mm portafilter holder for the cylindrical Turin SD40 single dose coffee grinder. The design is tested to fit Gaggia style 58mm portafilters with a 28mm tall dosing funnel (MiiCoffee Tall dosing funnel shown). It is also designed not to block use of the grinder's stock dosing cup.

The holder comes in two parts are requires 3 20mm M3 cap screws and 3 M3 nuts to come together.

The first part is the mount to the grinder that attaches like collar shaft style clamp. The nuts for attaching the portafilter mount must be installed first before attaching the clamp. The clamp must be tightened in place before adding the protafilter mount.

These steps result in an installation that almost completely conceals the M3 nuts and screw caps.

The clamp is designed to fit very tightly in order to avoid sliding and loosening during use. If you have trouble getting it on, try using a blow drying to carefully soften the clamp and expand its diameter on the grinder body.

This will work for any grinder model that uses the same cylindrical housing including the Turing SD40S, MiiCoffee D40, and Miicoffee D40+. This will not work with the square body versions of these grinders.

Successfully printed in Tough PLA with 3 perimeters and 25% infill for strength and flexibility. The grinder mount prints flat without supports, the portafilter holder can be printed vertically without supports.
