For hand cutting, a fretsaw like this works well https://www.zoro.co.uk/shop/hand-tools/saws---coping--fret-and-flexisaws/70-fs1r-(fs70)-fret-saw-frame/p/ZT1008912X?utm_campaign=pla-Hand+Tools+-+&utm_source=google&utm_medium=shopping-pla&utm_keyword=ZT1008912X&istCompanyId=6aa6787b-063e-4414-802d-129f235df603&istItemId=wtqirimrql&istBid=tztx&gclid=CjwKCAjw8uLcBRACEiwAaL6MSV9lVM_DLaM5FpAolUtZq-OsbX4HYDheciYjol_LahWtMPApc8EtvRoCYrgQAvD_BwE Then finish with a file. |

I built a front panel from two sheets of Acrylic with a paper printout from the CAD tool sandwiched in between. The actual drilling was done on a small converted CNC mill (Grizzly GO704). Sure glad I bought my mill before Trump tacked on a $345 tariff. http://www.grizzly.com/products/Mill-Drill-with-Stand/G0704 I plan to use the sandwich scheme in the future. It works well, looks nice and the lettering is protected by the top sheet of Acrylic. The good news is that I don't have any square openings. If I did, I would do as I suggested above and rough cut the opening with a large diameter cutter (to lessen the chance of breaking) and then clean it up with a small diameter cutter. If absolutely necessary, I could square up the remaining radius with a file but I would really like to avoid that. |

You can get a 90deg corner by overmilling in one direction slightly... |

Just get a broach tool and be done with it |
