Esun Refill Adapter for Bambu Lab Spools

I recently started using esun's refill for PLA+ (92.6mm in inside diamater) and spotted that no adapter is “good enough” if it comes to adapting them to bambu lab's spools that come with the printer. There are plenty of adapters on the market but none of them address the issue of huge gap between filament and sides of bambu's spool which might cause issues with unproper unwiding of the filament while printing. That's why I have decided to make adapter with spacer to keep the filament tight.Steps:open bambu lab spoolplace the 3d printed part into piece with small notch (there is a special groove for notch in the 3d printed model)put refill (do not remove cardboard straps)put other part of bambu spool and screw itremove paper strapsenjoy
