Summarythe roof is a bit difficult to print. I'm going to change it. Once printed, it works fine. Just too shallow for a printer to print nicely. That said, once I fix the roof, I will fix the hole. I forgot to cut a hole through one of the constituent components. Its a quick 2-3 mm layer that needs drilling. You can see in my orange printed version; my computer crashed half way through due to an accidental click on my behalf. Printed a bit and plastic welded it on. String trimmer line for a hanger, but the base is wide enough to survive sitting on a picnic table or something. I can't remember the exact dimensions, but roughly 200mm diameter and 200mm high.
