Ender 3 compatible eSun Refill spool

thingiverse

Hi all, I recently was searching the www for a master spool STL file for eSun PLA refill filament. One of the most promising spool was the one I found over at Prusa: https://www.prusaprinters.org/prints/55820-reusable-filament-spool-esun-and-inland-compatible Unfortunately the two spool models didn´t fit my Ender 3 build plate :-( Trying to print them in a diagonal postition resulted in tons of tree support being printed and print time far above one day. So I came up with my own crude hack: Using OpenSCAD I removed the outer rim of the spool and replaced it with a somewhat smaller spool rim which easily fits on the Ender 3 build plate. Since I am using paper clips to attach the filament to the spool while not printing I simple got rid of the multiple holes from the original spool. Since the OpenSCAD file is included as well as the source STL files you can simply add holes to the model yourself. OpenSCAD is pretty straight forward for chopping out parts of STL files and combining them to something new :-) All kudos go to Beaver, the original designer for this spool. BTW: Even if my version of the spool has a somewhat smaller in diameter it still fits the eSun refill packages flawlessly.
