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.
I’m very happy with my 50W Laser Cutter (see “Getting Control over a 50 Watt CO2 Laser Cutter from China“). My main decision factors were (and still are): Software, software, tools and again software, and down in the list finally the hardware. Same thing for that laser cutter. After several upgrades (see “50W Laser Cutter Upgrades“), it was time replace the stock controller hardware with a new one including LCD display:
