Description
A basic housing for an IR sensor. I got mine from Aliexpress, but some suppliers have slightly different layouts and sizes. It's supposed to be an MH series from flying fish, so it should be pretty standard, but of course who really knows what they'll change?
I used an M3x10 button head cap screw. You can use longer if you want it to extend out the bottom for attaching to things. The threads should self tap. So maybe run a screw through the lower portion before assembling.
You may have to fidget with the LEDs to get them aligned right, it just depends on how beat up/bent the leads are.
no supports, lay them on the bottom edge for the bottom and top for the top.
As always, let me know if you have questions or design change requests.
