I made a regular size one and then I enlarged it to the max that I could fit on my X1C build plate. Both printed excellent using iSANMATE PLA Silk filament.
I used iSANMATE Silk PLA that I got off of Amazon. The small one used their Rose Red/Blue and for the large one I used their Blue/Green filament. It's worked great so far.
I scaled it down to about 75% of its size and it printed perfectly fine with no issues at all. I used a simple PLA matte black and it turned out perfect.
