Here is a - Easy to print - Spoolweight for Filament Spools with 54 mm
for example used by ERYONE, TINMORRY, …

I filled it with round about 300g weights for Car Wheels. Filling could be done with other stuff too (rice, sand, screws, nuts, …)
No more jumping of nearly empty spools in the AMS.

Printed on a X1C in PETG (PETG recommended, because of temperature in the AMS when standing on the Bambu)
PLA might work too, but not tested
