This is an update to a hanging sleeve style case to support a Raspberry Pi 4, and allow you to attach your Octopi server to the bottom of your Ikea LACK enclosure, or to the wall of a cabinet, etc. It makes it easy to mount or unmount the Raspberry Pi for updates or maintenance without any tools. The design was originally inspired by the sleeve designs by Wilko, and I opened up the ventilation a little more, as well as provided access to the Raspberry Pi header pins to connect temp sensors, or relay control, etc.
The base of the sleeve is flared out to work with the included mounting bracket. The bracket is attached with four M3 wood screws and the sleeve easily slides in and out of the bracket. You can adjust the amount of friction holding the sleeve in the bracket by tightening or loosening the M3 screws holding the mount to the surface. Even if the fit is very loose, the sleeve is still held securely in the bracket with the USB Type-C power plug locking it into place.
You can refer to Hanging Raspberry Pi 3B+ Mounting Bracket and Sleeve Cases to see the previous design in-action mounted to the bottom of my LACK enclosure.
The example of the sleeve shown is printed in Prusa PET flat on the printbed. I added supports “Everywhere," and adjusted the Support material settings for Grid “Style” supports at a 45 degree “Pattern angle,” and 0(off) “Top interface layers.” This kept the top clean and made the supports easy to clean out with a pair of needle nose pliers.
The author remixed this model.
Adjusted dimensions of previous design to fit Raspberry Pi 4B.
