eSun Cardboard Spool - Hex Pattern Reuseable Spool

First measure you eSun Spool, before printing and definitely before ripping apart the spool!Measure the spool core width and if possible the spool core diameter ( it is hard without the right tool,but there are some tools online at Makerworld).This spool is not(!) for eSun Refill Spools. Some recently bought eSun cardboard spools (PLA+/ePLA) could not be used on a Bambu Labs reuseable spool(if you remove the cardboard walls), first I had to glue the sides together again. But after one fall off I hadto search for a other solution.I created this spool with following parameters:spool diameter: 200mmspool core diameter: 75.7mmspool hole diameter: 55mmspool core width: 58.2mmspool side thickness: 2.4mm.applied some holes to save materialI applied a 10mm honeycomb cutout pattern.If fits perfectly into the Bambu AMS.If you print it with PLA, do not use the spool in a filament dryer .. it will deform.If drying is a topic then print it in ABS. But I did not get spools from eSun except PLA/ePLA,
