D810 delta 2020 bed brace

Whilst printing, I noticed that my bed was being pushed sideways by the nozzle, resulting in a bit of distortion to the print. So I designed these braces to screw to the bottom 2020 extrusion to lock the bed in place horizontally, but still allow vertical movement for bed levelling.

Designed for the Zonestar D810, but possibly will work (with a bit of packing perhaps) for other delta pri
