Slim Junction Boxes

The following instruction is only useful for electrically talented people. No liability is assumed for damages resulting from this!

At my laser cutter I wanted to separate the control lines to the x- and y-control motors and the laser from the wiring harness. However, I didn't want to have heat shrink tubing in the cable drag chains and unsightly junction boxes.
The result are slim (for 20 mm aluminium profile) junction boxes with 4-, 8- and 16-pole connections. The screwable (M3x5mm) connections consist of solder tags and can be doubled per contact.
The threads are cut directly into the PLA using an M3 tap. If required, the mounting surface can be protected against short circuits with a strip of insulating tape. In general, the slim junction boxes should only be used for lower voltages and currents!
