Do not screw you electrical parts on a wooden board. Do it the right way, with a DIN-Rail!
With this mount your Arduino Mega 2560 sits perfectly in your electrical cabinet, like it was from a 'professional' machine!

1st. gen on the pictures. I changed i a bit for better print quality. New pictures soon.
2nd Gen had a wrong pocket. Fixed in Gen3!

v3.1 removed two pockets for more continuous printing.

v4.0 should be the final version. Tell me when you need something changed.


I have constructed an arched window to support the last layers,
when the part is printed.
Please turn the STL on it´s left side before printing. (arcs on top..)

what about adding some standoff for the arduino say 3mm height and use hex nut on the base ?

Can you redesign it so you can snap on or clip arduino and not use screws.

Great, thank you for the picture. I will update the design for UNO/Leonardo/Zero the next days. Cheers

Part came out great! Any chance you could do one for a regular sized Arduino?

Hey guys, I have constructed an arched window to support the last layers,
when the part is printed. I thought it was obvious, that this defines the
Of course this part has to be laid on its left side (arcs on top..), before beenig printed.
I am sorry for the misunderstanding.

I tried printing it as shown - not very successful. The supports were too hard to remove. I think I will retry on it's side.

The STL file is not oriented well for printing without a lot of supports it seems. Did you print it like that? I can't decide whether I should print it with the flat down, or on it's side.
