In my past (unpublished) revisions, PLA has worked for 2 years of winter use. I've now beefed up the legs so they're not so fragile and break and a few further tweaks to stop it being as loose.
I'm now using 3dtomorrow's BioPro as an alternative to ABS/PETG so these should be suitable for any road use.
Print settings shouldn't matter, but I'm using 30% infill, 4 walls, top & bottom. This should make the legs solid which will be the most important.
Nov'24 model has been tweaked to fit 65mm face (so will work with stick-on logos from ebay etc)
The author marked this model as their own original creation.
