AMS Weight for Kingroon filament rolls

This is a weight holder for spools.  It is intended to be used in the BambuLab AMS.  When the spools get low on filament they sometimes lift up when filament is being pulled from them.  With this inserted it helps the spools roll as intended.   The main body is hollow and closed at the top, so you should insert a pause at 66.4mm and insert the weight, then continue the print.  This is done so the weight will not fallout when unscrewing it.  The pause height might change slightly depending on the layer height you print it at.  The weight I used is this one:

I used these steel ball bearings for weight

I printed these at 0.2mm layer height and no supports. 3 walls and 8% gyroid infill.

All credits go to the original designer, I merely resized to match my usual brands roll.
