THOR210 frame - side protection

Gives a bit of additional toughness to the THOR210 frame (with 30mm spacers), and as a bonus - some protection from dust.

This design is for rear battery connector setup. (i.e.This PDB fits perfect: http://www.banggood.com/Realacc-Matek-PDB-XPW-5V-12V-Dual-BEC-PDB-Built-in-140A-Current-Sensor-with-XT60PW-Socket-p-1111981.html).

This is right side protection detail. To make detail for left side - just make a mirror in Cura ot whatevere slicer...
