Mikrotik RB931m 2nD (hAP mini) DIN rail case

WARNING. This may void warranty. I mean, yeah, it's going to void it :)

Original case does look nice but it's a real pain to mount it somewhere.

I printed this in PETG at 0.2 mm layer height.

For printing the small LED light guides I used transparent PETG and it kind of worked. If you don't have a multicolor capable printer, just remove the object named “LED” and you should have 2 holes left in the case instead.

To be able to fit the PCB inside the case I had to shorten the 2 pins that are part of RJ45 connectors, the rest can stay as it is, no further modification is necessary. You could also just bend the pins a bit, should also work.

Tolerances are quite tight so I only suggest printing this on a well calibrated printer.

The numbers 123 were added in Bambu Slicer before printing.

Oh, in order to remove the PCB from original case, just use a flat screwdriver and jam it into bottom hole and twist it a bit. I used 2 LAN cables that I connected to ports 1 and 3 and pulled everything out rather gently.

Clip is also updated in the 3mf file, the one on photos is a bit short.

You only need to support part of case where clip slides in. The clip slides into case part from inside-out so it can't fall out while mounted on a DIN rail.

Oh right, I didn't make any holes for “Reset” and “Mode” buttons on purpose, you can still edit the model and make them :)

You will also need 2 small screws so you can fit back plate into case part.
