[sdiy] disgusting sticky rubber wheels solution found

[Florian Anwander]

I talked to someone who is doing enclosure manufacturing, and he said, 
that basically the idea of using those soft plastics isn't good. Those 
materials require so called plasticizers (softeners). These diffuse 
towards the surface at room temperature, where they then evaporate - 
normally. If the material is not ventilated, the plasticizers dissolve 
the top layer of the plastic quite quickly, which then becomes sticky. 
If the material can ventilate, it becomes brittle and fragile. Neither 
is a good option.
