Rollweight for third party AMS filament spindle

In my bambu AMS I use apart from original bambu spools also spools from other companies that deliver filament on spools that fit in the bambu AMS but are not the original bambu spools.

The weight of these third party spools is lower than the original bambu spool, which has the disadvantage that rolling up the filament doesn’t work if the filament roll is half way.

Therefore I designed this thing. A cylinder with a sheet of lead, that has enough weight that you don’t need to help the AMS to roll up the filament anymore. Just put it in the hole of the spool. The spool hole size must be 52,3 mm.
