Excelvan hub for BobsCNC RP9

thingiverse

THIS IS AN OLDER VERSION - the newer version is here, though be warned that it is untested:http://www.thingiverse.com/thing:1723705 I like Excelvan filament. I don't like how big their spool's hub opening is. My spools would drag on the table when using my printer's included spool holder. So... This adapter neatly snaps into the Excelvan's hole (print two - one for each side) and reduces the diameter of the hole significantly. The adapter should be reusable if you carefully remove it. I've done so without delaminating and mine are printed in PLA. The print is simple and shouldn't take super long. I actually print without my cooling fans in hopes that inter-layer adhesion is improved. The result is still extremely clean looking. Hope this helps someone out there! This thing was made with Tinkercad.

Supports are most definitely not needed nor helpful. A raft can be very helpful as there is quite a bit of surface area on this model holding it to the print bed. 0.2 mm air gap on the raft allows me to take them off the print quite cleanly.
