Left and Right parts for a small version (SL/SR) and a big version (LL/LR) with a common bar so you can fit most plates.

Allowed to be printed on a 150 mm print surface, but rotate 45 degrees to print each part diagonal.

The STL files reports an error when opening it, just click repair or use the FPP files instead.

Make sure to use more Infill on heavy plates!
