I took a fine battery tray from @walter and imported it to sketchup, cleaned it up quite a bit and then used the fabulous "RoundCorner" Plugin by Fredo6 to smooth the edges.
Took me about 2 hours or so. Most of that was manually cleaning extra lines from the model so the roundcorner plugin would make smooth curves without extra holes etc.
The upper outside edges are set to have radius 0,4mm and all other edges 1mm.
I hope you like it and props to walter for the original model that I used as a source.
