These are my favorite tools!

Tap and Die Set Metric | M3, M4, M5, M6, M7, M8, M10, M12

This metric tap and die set works great for Vectrex stuff! I've used it to create new joystick knobs and repair threads on joystick shafts. You get a metal thread pitch feeler gauge with the kit so you'll know exactly which tap or die to use.

Torx Driver T-10

This is perfect for the 8BitDo Arcade Stick, VEXTREME, and other things. T-10 is a pretty common size.

PCB Chamfering Tool

If you don't want to pay for your PCBs to be chamfered to 45 degrees, this tool can let you do the manual labor and probably a better job anyway. The CNC at the PCB board houses do tend to leave a sharp edge on the chamfers even when you do pay for them to be done... so this can also help dress those up in a very uniform way. I like to use 400 grit for that purpose.
