UPDATE: I edited the cover model (v2) for improved screw fitment. Increased the chamfer to better recess a common M3 x 8mm flat head. Using this model (purchased from local hardware, not Amazon) in the new image uploaded…

UPDATE2: Added a non-rounded version (use the same back cover).
ORIGINAL: Lot of beer tap handles, but I liked the appearance of the round model from @wrelsien_105024, but needed to fix a few things. Just needs one small screw to hold the back cover on, one 3/18-16 nut, and a passive eInk display. Not sure what screws I'm using to attach the cover, they're ~3mm c 8mm with a chamfered Phillips head. Using standard 3/18-16 nuts. I'm using Waveshare 2.66inch e-Paper Modules that came with zero documentation. Thankfully their site is pretty helpful…

The app feels extremely unfinished, but it works well once you figure out the basics. Much easier to create your display images elsewhere and only use the app to upload to the module IMO.
Printing is pretty simple, with no supports needed. I like the way shiny or dual color prints look using the Octogram Spiral bottom/top layer infill patterns as you can see in the pics. Still want to test with some wood filaments but haven't had a chance yet.
