this was done at the school shop with a tinkerine printer, (marlin Cartesian)

your printer must be well configured for this to work, the tolerances are very tight, i have not had any luck yet on my own delta printer

even after you get a good print, you will spend a few hours running it around to smooth out and free up the rollers

with a good printer it can be scaled to 50%
