After the latest upgrades to my TronXY X5S (https://burningbecks.wordpress.com/tag/x5s/) the bits box was full of RepRap components. The main reason for starting building with the P3Steel frame was to put some parts, still too good to be just thrown away, into use again. The panel of the "Sumpod" (https://burningbecks.wordpress.com/tag/sumpod/) is a very specific part and I don't think anyone can use this STL out of the box. But I like that "Open Hardware" logo, so here are the sources anyway. ;-) Pictures show the previous version. (Corrected some dimensions without re-printing.)
