This is an easy to print shelf for your shower.
I designed this in OpenSCAD because most standard metal shower shelfs tend to be rather small.
Preferably, do not print this in standard PLA as PLA will not be able to withstand the temperature of hot water without warping.
I have printed this in PETG and it is holding up just fine, even when rinsing it of with hot tapwater (which usually is no more than 65-70 degrees Centigrade).
I have uploaded both a 200mm model (which I use) and a smaller 150 mm model.
