I printed a test set of 4 using PLA and a 5mm brim (at 200C / 60C temps) -- all the features printed very well. They were stiff to assemble, but clicked into place fine, and moved very smoothly once assembled. So, I started printing a set of 24 (6 sets of 4). 8 1/2 hours into the print, still only 60% done. I had no problems with first layers while starting the print.
