After you've gone in for a replacement for the original spool holder (I replaced mine to make room in an enclosure), you are left with the original spool holder. A build here on this site provided the basis for this remix. This one simply makes the original snap apart into three pieces - two brackets (identical) and a mount bar (short). Prints in place as assembled bracket, later comes apart after you print it.
With or without supports - depending on how well you handle bridges. if supports, only on print bed. Everything else draft default
The author remixed this model.
