Cutting out a micro usb port cleanly

[BrownZeus]

Does anyone have any tips or tricks to cleanly cut out a microusb port in plastic?

I have raspberry pi project that I have in a more or less custom platic enclosure, I just want to cleanly have access to the microusb port to power the project. the hole is too small for a router or drill bit to do the cut

A 3mm or 1/8" milling bit will work.

I don’t know what tools you have to work with, but you could start with a small drill bit and then clean up the edges with fine files.

last time i put a hole for a micro usb port in a project i just drilled a 6mm hole and squared it out, then mounted the board about 5mm deep in the enclosure. result: the hole is now also strain relief for the connector.

 

as for actually cutting a micro usb sized hole cleanly.. you need some fine tools to make such a small rectangular-ish hole. if the plastic isnt too hard and too thick, just a very sharp boxcutter will probably come close.

Use a Dremel or needle files.
