38mm diameter filament spool bracket for replicator

thingiverse

To ensure proper fitting of filament spools, note that MakerBot originals measure 50mm, whereas most Chinese-made alternatives have a 38mm center hole diameter. To use these smaller spools, consider the following steps: firstly, select exterior support when generating Gcode; secondly, maximize infill at around 50% for increased extrusion time; thirdly, utilize a raft and set platform temperature to 110C; lastly, prevent filament jams during extruding. However, be aware that output issues may still arise due to weak support materials, so use kapton tape as required to secure parts to the platform for successful printing every time.
