2020 Extrusion Vertical Screwdown Support

Vertical support to be screwed down to a base board. Holes are 3mm with countersink. Vertical side has a rectangularpiece to fit into the slot to stop sideways movement but won't lock front/back, so use another support on the opposite or adjacent side if you have room.

Edit: widened rear insert (2) & added clips (1) to lock in to cutout.
