Bottomless Portafilter Tamping Stand, Modular and Adjustable

I needed a stand for prepping my espresso shot using a bottomless portafilter. This model is designed around a Normacore 54mm portafilter but you can adjust the basket holder and handle holder parts to fit yours with the included Fusion 360 files. This particular portafilter is not self supporting. The parts are threaded with so you can adjust them up and down to get the level correct for your setup.  A secondary consideration was that I needed it to work with the Umikot V2 WDT 54mm which most of the existing designs I reviewed would not.

I printed the handle holder threads up with support under the arch.  The basket holder was printed with the flat side down, threads up.  

The base was printed with no top or bottom layer and an honeycomb infill line width equaling 0.8mm at about 15% fill.  This allows any overflow grounds to fall through to the mat I use for easy cleanup.
