Summary

Mk3 front frame for P3 color matrices. A special type of fastening of matrices, which I have not seen before - matrices are held by 16 pin connectors on both sides. The front frame is only compatible with the protogen mk3 from my workshop. The model does not fit on a table 220/220mm, it is necessary in one of the directions 240-250mm to accommodate the frame.

The 3d model of the matrix itself is in the profile, you can use it for any purpose.
