Version 1.2 (2025-03-12)

• Added TPU inset print option
• fixed some bugs
• updated description

Well, it has been some years already that this box model is online, and that people seem to like and use it. Always happy as a designer to see that happen.

Recently, a reader suggested to add an option for a (TPU) inset model so that the oddly shaped isolation rubber for the "ditch" could be self-printed. I absolutely see this as a great idea and added it.

There are now two more Customizer parameters:

1. TPU inset: Setting this to non-zero adds the model for the rectangular "ring" meant to be printed with TPU/TPE/soft material. The parameter sets the height for this inset, and at the same time reduces the wall height on the main box model for the same amount.
2. TPU inset X/Y reduction: Setting this parameter to non-zero reduces the width of the TPU model so that it can be installed easier into the ditch.

Version 1.1 (2016-08-21)

• added customizer tags and made it customizable
• added screw holes (either 2 or 4)
• fixed some bugs
• updated description

Version 1

This is my OpenSCAD universal case box for electronics. It comes with round corners, mounting noses, easy dimension settings and a lid that closes the box waterproof if applied with some sealant (hot glue or -less permanent- bicycle mouting grease).

Note that the standard plastics (ABS, PLA, PETG, Nylon) degrade in UV light. Do not expose the box to direct sunlight.

A note on the cable holes: customizer allows you to view the source code. Press the "View Code" button next to the "Create Thing" button. Then, find the section commented with

// **************************// ** YOUR OWN CUTOUTS HERE!// **************************

and

// **************************// ** / CUTOUTS// **************************

There, you can remove the two already there and add your own.

• Print in any desired color or material.
• Adjust the barrierTolerance global constant to make the "ditch" on the lid wider than its counterpart on the box.
• I'd recommend printing with brim for ABS. Since it's round corners, the stress is not as high as with pointy ones, but still.
