After looking for a vertically-oriented portafilter for a while, I didn't find any that convinced me, so as my first CAD project I decided to create one myself.

The tamping station has space for the following:

• Portafilter.
• 58-58.5mm tamper
• Umikot WDT tool. (see https://makerworld.com/en/models/169731#profileId-186634)
• 2 58mm puck screens

I will upload a version with an extra 60mm space instead of the umikot one soon.

Since I already had another tamping station, I added a hole for the portafilter handle rising screw, if you don't have one, you'll need to find a way to rise your portafilter handle for perfect support.
