This is a DIN Rail mount for SONOFF Mini relay modules.
It is based on the 3D Model provided by SONOFF here, and I have used it with the ZBMINIR2, but according to the manufacturer, it should be compatible with the following modules (and maybe others that share the same dimensions):
MINIR4M (Matter version)
MINIR4 (Wi-Fi version)
ZBMINIR2 (Zigbee version)
MINI-RBS (Matter version)
MINI-ZBRBS (Zigbee version)
Note that the SONOFF MINIR2 (non ZB) has a different form factor.
Revisions
There are 2 versions of the mount, the difference being the clip.
In the original version, the DIN Rail clip is based on the following model, it works, but I found it to be hard to fit on a limited number of DIN rails that have pretty loose tolerances: https://www.printables.com/model/64242-din-rail-clip
In V2, the DIN clip is based on the clip used by the Voron project for the components of the electronics bay, it should be easier to fit on any DIN rail: https://vorondesign.com/ or https://www.printables.com/model/541598-wider-pcb-din-clip-voron-0
Printing parameters
Prints fine with standard printing settings:
0,4mm nozzle
0,2mm layer height
3 walls
~20% infill
For this type of piece, PETG is advised.
