These mounts are intended to wrap around the outside of the t620, and interlock with the next stacked horizontal t620 & t620 plus. As these (except the t620 plus) are passively cooled, I found when I have these stacked horizontally there is some heat generated. This bracket allows for some cooling and organisation.
PETG/PLA
20% infill
Infill: lines
BPA: Brim - inside only (easy to slice out with a knife)
--------
In the plus version I removed all the cut outs due to print quality, and controlling material use with infill % in slicer.
