These files allow you to hold an Inky Impression inside an Ikea RÖDALM frame and mount it to the wall, with enough clearance for a Raspberry Pi Zero with a WittyPi Hat. The frame is attached to the wall mount using some slides, allowing it to be easily removed for charging the battery.

The model files were made in onShape and can be found here if you wish to tweak them. https://cad.onshape.com/documents/4913049a9a49f8f4cdaf3a0f/w/25e13eeb061b24291810236e/e/7fa965596a244ea4fc1d81bc?renderMode=0&uiState=6983d51955dd59293dddc37a

I also wrote some code to handle updating images on the display on a cycle, keeping the pi powered off between updates. You can find it on GitHub, along with instructions on how to install everything.

Print Settings

All these parts can be printed in PLA and on any bed at least 200x200mm in size, such as the Bambu Lab A1 or Prusa Core One.

I printed using a .4mm nozzle with a .28mm layer height and 15% infill, but I don't see a reason you couldn't print these using a bigger nozzle.

Due to the overhangs, I would recommend using support for the slides, frame_insert and wall_hanger-wall_mount.

The pi_support and battery_holder can be printed in any colour, but the other parts will be visible so should probably be all printed in a matching colour that either matches your frame or your wall.
