I wanted a good DIN Mount for my Shelly Switches to mount them properly into my electrical box, but all that i found did not really satisfy me.

So i made my own inspired by severel other designs with these key features:

• vertical orientation to save space
• needs to be compatible with “common” DIN Rail box standards
• toolless wire teminals

Print Instructions

Print in 0.2mm for the integrated support on the Main Body to work, you need to remove the purple Support after printing with a screwdriver or similar tool.

Assembly Instructions:

For each Mount you need 4 x Wago 221-413 Terminals and some wires.

1. Slide in the Wago Terminals vom the side ⅔  of the Way so you can still open all latches
   
2. feed through the wires from the inside to the outside without cutting it form the spool and strip ~8mm of wire on the outside
   
3. Put the stripped wire into the bottom wago port, close the latch and push that terminal all the way down
   
4. Repeat that process with all 4 Ports (Recommended colors: N: Blue, S: Black, O: Brown, S: White)
   Pull all the Wires, that are still connected to the Spools gently tight like in the picture and cut them roughly to the length where me finger holds the wire
   
5. Wire up the wires to the Shelly (O: Brown, L: Black, N: Blue, SW: White)
   
6. Push the shelly into the cavity with the wires beneath it, make sure now wires stick out anywhere
   
   
7. Remove the support structure and slide in the Lock like this:
