3x PCB holder

This compilation contains three 'snap in' PCB holders with different sizes, but 1.5mm thickness:

26.3mm x 51.0mm is for commonly DCDC converters (sorry for the typo in file name),
43.4mm x 43.4mm is for commonly used L298 dual H-bridge motor driver board,
40mm x 60mm is for commonly used prototype PCBs.

There is 3mm free below the PCB. Only 4mm x 4mm in it's edges is occupied by the stand, where usually the mounting holes are situated.
There is a single mounting hole for 3mm diameter screws in the centre.

The overall size can be seen in the JPGs.
