Lego - Powered up hub bottom cover

thingiverse

Bottom case for LEGO powered up hub when using 2S lithium polymer or lithium ion batteries.  There are 2 versions, one that is 1 brick & 1 plate high without bottom holes for studs and there is one version that is 3.2mm higher for studs. There are also two versions of bottom with studs. One with 5.1mm and another with 5.2mm holes. I think my 3d printer is pretty much dialed in and I find that 5.1mm is a very tight fit and 5.2 is a bit loser fit.Update: There are now another version with JST RCY male plug in the bottom case. It's not a 100% fit without some work. So this version is work in progress, but you can make it fit if you trim the grey plastic through holes for the A and B port right above the JST plug.
