Cable hole.

Need a nice way to get your cables through the kitchen counter? Perhaps your makers cables through your desk? my contraption handles 40 mm thick plates.

1: Print the parts, no support needed.
2: While your parts print. drill a hole > 50 mm (i used a 53 mm hole saw.)
3: The collar goes underneath the your desk. The pipe goes through.
4: Thread the pipe into the collar
5 Put your cables through
6 Lid goes in after the cables

Just used it in my kitchen, transperant plastic.
