In cased you need a drill press without any fuss, just print these two files in PETG and buy a 10mm rod to be cut in 4 pieces (you can find it in every grocery/DYI store). It's not an industrial precision tool but if you want to crave an hole and it needs to be vertical this works. The 4 rods may be glued into the base.

Functional, less than 3$ cost.

The design of the body .3mf is adapted to Einhell driller, the cheap one, but if you need just adapt the driller pocket, this one is 44mm diameter hole, like most drillers. In case not ask more diameters in the comments I'll be happy to help uploading base .3mf for your use.

I'd suggest 3 wall loops, at least 20% infill, no support needed of course.
