About 5 hours printing. Some few minutes cleaning it up.
There's a thread where we discussed what it takes to actually make the ABCards, btw.
(FYI: the printer runs at 30 mm/s for that 'quality'. I haven't played much with the speed. I will when I rebuild the carriage to use all bearings instead of the delron blocks it's using for support on two rods. The guys in the printer forum -say- I can go up to 150 mm/s, same quality, if I fix the carriage. We will see...)
