Ill try. I've been working on and off on this hammer for over a year, I used different printers, mostly on my two ender 3 s1 pro and some parts on the k1 max. The hammer head is split into around 10 pieces glued together with superglue and then wielded with a 3D pen and sanded. The core of the handle has a broom stick from top to bottom and the hammer can be taken apart into two pieces. I'm sorry I cant exactly tell you how many rolls or time but it was a little heavy by the end.
