Not specifically for Arcade purposes, but the reason for this print will be Arcade related. C
Couldn’t find a housing for the 16 channel relay board sold from Martin P Jones and Associates Inc. So I drew my own. No supports required, and easy print in PLA. See here, for how I’m using mine in the arcade
The relay board size is 1 79 mm x 89.5 mm
The base plate has provisions for 6-32 nuts to be inserted from underneath. Likewise, the holes for mounting the completed unit are also for a number six screw.
The top requires for 6-32 x 7/8 socket head cap screw for mounting the top to the base. The 16 holes running down the center provide a line of sight to the corresponding relays LEDs

Flip the base part over and press in the 6-32 nuts. If necessary, add a dot of super glue to hold them in place.
Place the relay board into the base plate, observing the fact that there is a cut out, in the base, for the double row header. If you flip the board 180°, it won’t seat properly. Snap the tap onto the base insecure with your 6-32 x 7/8 socket head cap screws.
This design, as well as previous designs, was done in Autodesk’s free 123D design. This is now an abandoned piece of software, that I am still very proficient in. You can download its last revision for Windows (2.2.14) here, but understand that the online cloud storage option no longer works.
The .123dx file may contain sketches, solids, or both needed to render the final STL. and is included to ease part modification for your purpose.
