Brackets Corner and 90 - 3D Printer enclosure or boxes - corner 3 nuts reinforced

Made this brackets for my 3D printer enclosure, printed in PLA, but it's suitable for ABS PETG and more.

If you don't resize you can use M3 nuts that fit perfectly on the holes with 10mm screws the same I used.

The acrylic I used for the enclosure walls is 2mm tick but you can use ticker.
