Pro tip for you budding CAD guys, You cannot laser cut a hole smaller than the thickness of the material.
If it's 10mm plate you can't cut a 9mm hole, laser cutters don't like it and the hole ends up tappered.
Don't laser cut a tapping size hole into your laser cut plate either, you will kill Taps very quickly and Taps aren't cheap. Laser cutting hardens the cut edge of the material.
While on tapping, Don't use "Goliath" brand of taps EVER..... I have had lots of problems with them back cutting the thread when removing the tap and won't use them period.
Counter sink EVERY hole all the time and ALWAYS counter sink before tapping anything.
Counter sink 0.5mm bigger in Ø than what your tapping size is. eg M10, counter sink so that the Ø equals 10.5mm
