I combined the clip mechanism from the Ryobi FastTrack Hanger by AJ60 with the battery housing from Pelphry17's Ryobi GearTrack Battery Hanger to allow me to store my Ryobi batteries on my Rubbermaid FastTrack system.

I created multiple copies of this on my Ender3 v2 at .2 with various levels of infill and varying number of walls. Like many other objects, the number of walls seems to make a greater difference than the amount of infill.

I used a brim for a few of the attempts but it shouldn't be needed.
