not all rubber bands are created equal. the better ones to use
are the Plastibands, orthodontic elastics and EPDM ones. These types will
on the average last for about 30 cycles before breaking. The Plastibands
will stretch out before they break.They are good for about 20 cycles
before it comes time to replace them. The EPDM are the best, lasting
around 26-30 cycles before breaking.
5 piece design and should take 5-6 hours to print.
