About this model

This is a box for a popular PC817 opto-isolator module PCB. Handy for a bunch of arduino/etc projects. With holes for small zipties for securing cable. Use 2x M2 5mm screws for holding the top of the box. I printed on a Bambu P1S, using ABS. Seemed to work well. If you find it useful, please drop a like or a comment. If you find it's a swing and a miss or fundamentally wrong, uh, please also leave a comment!
