Laser-cut MCU-Link Pro Enclosure for the Masses

With “Adding RGBW Wings and Enclosure to a Debug Probe” I have a really shiny enclosure for the MCU-Link Pro Enclosure.

But I did not had enough time to replicate this for a full set of classroom hardware. The original card boxes from NXP showed already after one semester severe wear, so I have to setup something more robust: a box to store all the cables, and an enclosure to protect the PCB, for 40 units.

3D printing would take to much time, so I ended up with buying storage boxes and creating an laser-cut acrylic (PMMA) enclosure for the debug probe itself:

Different Laser-Cut Enclosures for the MCU-Link

The MCU-Link debug probe comes without an enclosure. To protect the hardware against ESD issues, I had created a 3D printed enclosure for it. That one worked fine, but takes some time to print it. If you have to build many enclosures for a full classroom setup, then a laser cutter is much faster. And to create some variations, I have decided to cut it with different materials and colors. To be environment friendly, extra glue is needed, and with recycled PMMA, different colors are possible too.
