I made this because i could not find any models online to print off a bread board and shipping takes to long for what i was needing to make a diy project for. This holds up pretty good for wiring a motor or led lights . maybe even switches for a little fan. I am using to make a extender block for my ender 3 pro and ender 5 plus. for longer cables and wanted something i could zip tie on the machine somewhere and not have wires everywhere and i could easily get to.
