Bezel for 0.96" 128x64 I2C OLED display module

These little OLED displays are super-useful. But mounting them into an enclosure means cutting a really neat rectangular hole, which I find slow & tiresome. This bezel holds the entire module on the outside of the enclosure, and fits with just 4 drill holes and another rough slot to let the I2C header through to the inside the the box.

Threaded inserts from the back mean there's no mounting screws visible from the front. There's a small notch at the middle of both top and bottom edge for easy alignment

It prints in two pieces with no supports. The back is press-fit holding the module in firmly. Inserting the top edge first can be helpful if your print turns out especially tight.

In the images where I printed on a textured build plate, I've matched that texture on the sides with Fuzzy Skin set to 0.2mm for both thickness and point distance.

I used a 0.20mm structural preset. These are in eSun black PLA+. The holes for the threaded inserts are 4mm and suit inserts that are 3mm deep. I used M3 as it's my enclosure go-to size, but there are M2 & M2.5 I've seen that also fit this size hole if that's your preference

Mounting The Bezel 

Update 28 Dec 25: I've also uploaded a physical drill guide you can print as an STL and use to cut these holes and slot into your enclosure to mount the OLED

Drill spacing in the above guide are to centres.
