3DR Large Spool Adapters

youmagine

This adapter allows the use of spools with internal diameter of 52mm on the RichRap 3DR.The tall piece should slip directly over the original spool holder with bearing.The spacer piece lifts the whole spool above the idler bearing covers if the spool is also too wide to fit in the standard slot.Printing should be very straightforward for both, use whatever setting you find most economical.
