Hygrometer Spool Adapter

This model is a small holder for a hygrometer so you can place it inside of a spool when drying that spool. I modeled it to fit with https://makerworld.com/en/models/36802#profileId-35070 but it also fits inside the official Bambu spools (not snugly but for most drying applications that doesn't matter). The hygrometer I used is a fairly default round one (amazon is filled with them or you can get them in the Bambulab store). Outer rim has a diameter of 45.2mm and the inner ring is at 41.3mm
