Very well thought out. Thanks mate! You can also use the tray with top cap (pictured) underneath and you don't have to cut any trays. That means there's only space for one roll, but you can print another set of spacers and stack them to fit two rolls. Otherwise, cut them as instructed. Note, the stringing in the pictures on the internal walls was from my first foray into PETG. The stock Bambulab profile is too fast, possibly needs to be cut in half at least and pressure advance calibrated if you're having troubles. Printed in Bambulab PETG Grey.

Fits perfectly for my silvercrest dehydrator and can print one spacer on top of another to be able to fit more than 1 spool without cutting the trays
