Adjustable Portafilter Stand

Description/Motivation

I wanted a way to grind from my Timemore 078s directly into a Gaggia Classic portafilter. I have a few different 58 mm portafilters that didn't necessarily line up with other stands so I designed one that can adjust to them all - there's even enough room for the stock double-spout portafilter, and it's strong enough to use as a tamping station. This pairs well with my Dosing Funnel.

Printing

PETG for preheated portafilter compatibility, 0.4 mm nozzle/line width, 0.2 mm layers, 3 wall lines, 20% fill, print per model orientation. Support recommended for the magnet area. 

There are two different support screws - one for handles that come off the portafilter fairly straight (need higher support) and one for handles that drop down off the portafilter (need lower support).

I've measured the threads on the screws I printed (M12x1 mm) so if your printer is printing to dimension they should work perfectly. That being said, every printer/slicer is a bit different so you may need to change slicing tolerance or slightly scale horizontally for a better fit.

Parts (optional, for Timemore self-centering)

• 20x3 mm disc magnet
• Gel super glue (cyanoacrylate) or epoxy

Additional Info

The stand uses a 20x3 mm disc magnet on the bottom to self-center under the Timemore and I've designed a locking screw (which screws in from the backside) if you want to lock the support to a single height. 

Bonus feature - you can also pick up the whole stand/portafilter/funnel stack from a pinch point.
