PCB soldering support

Clips to the side of a through hole plated PCB, to raise it off of the workbench and allow through hole components to be placed and soldered from the top, before clipping the component leads and final soldering on the underside of the PCB.
Use e.g. Cura slicer and scale the length as required.
Use as many as required, e.g. print 4 at 15mm long to support 4 corners, or 2 at 60mm long to support 2 longer edges.
Works best on a silicon soldering mat, which prevents the supports from sliding around.
