CR-10 Top Rail Filament Holder (WIP)

thingiverse

This spool holder inserts smoothly into racing stripe grooves on the top rail, utilizing the standard spool threaded cylinder that comes with the printer as is. I may upgrade to a printed cylinder later on, but for now, you can simply heat the top of the part using a hair dryer (or hot water), then screw the cylinder directly into place.\r\n\r\nI strongly advise printing the test file first to ensure it fits properly.
