eSun e-PLA Matte > Bambu Lab reusable spool gap filler

prusaprinters

This is an adapter ring used to fill the gap on the Bambu Lab spool when transferring eSun e-PLA Matte, or other thinner or less quantity filaments, to it. The inner cardboard ring of the eSun e-PLA Matte filament is the perfect size to snugly fit over the Bambu reusable spool, but the eSun spool and filament winding is slightly narrower leaving a small 4 to 5 mm gap. I think we all know what kind of problems can arise from this gap.This spool gap filler ring should be placed on the side of the Bambu spool that does not have the notch, its the side with the shorter center piece. Print in Petg, or better, to ensure heat resistance when drying your filament and use your preferred settings. If you live in an area where you don't have to dry filament, PLA should work just fine. I've only tested this with the eSun e-PLA Matte so I'm not sure what other filaments it may work with. you might even be able to scale the Z height higher to make it thicker so you can transfer .75 or .5KG rolls onto the Bambu spools.
