This is one of the upper arms. you will need to mirror it to get the other one.
printing time on Prusa I3 with 40mm/s and 0.4 nozzle about 40 hours.
the lower arms will follow.
Then I need to stop for a while because my printer just bruned and I Need to order a new one.
So always be careful and maybe put some fuses and extra cooling to your printer ;-)
