I've been playing too!
Is this acceptable ...
I've had to cut the top off a little.? The original stl is around 1000mm high.? If I scale it to 100mm I think the wall thickness will be around 2mm.? You should be able to re-scale in a slicer.? If the ratio is OK I'll see if I can create a printable file, but I think it's going to have to be another stl.
