I needed to drill a whole in my desk with a 16 mm spade drill as perpendicular to the desk top as possible. Freehand sounded scary so I've created this little guide. It works for drill bits with 7-8 shanks. I've prepared guides for 16, 18, 20, 22, 25 and 32 mm. If you need some other sizes - let me know.
Tested with 16 mm.
No special print parameters, 20% infill to be on the safe side :)
