This is a Wago 221-415 Mount for my DIN Rail Bracket. You can find the bracket here!
There are several versions, for 2, 4, 6, 8, 10 and 12 Wagos.
STL and STEP files are without labels and can be edited to your needs.
For the DIN Rail Bracket Mount you need M3 countersunk screws.
The author marked this model as their own original creation.
