Bambu Labs AMS Sunlu 250g Weighted Adapter

I made this to solve issues I had with other adapters for Bambu AMS/Sunlu 250g spools, specifically when the spools are less full, they are not stable enough and lead to many feeding problems that require manual intervention/opening the top of the AMS. 

✅ Exact same size as BambuLabs spools (200mm x 70mm). Wider than most other adapters giving the spool more horizontal stability. 

✅ Notch to make a solid connection between the spool and the adapter. Other adapters use friction alone.

✅ Hub is specifically modeled to fit a D-cell battery giving it extra weight to keep it stable when filament is low.

✅ Hub is porous to use less filament and so you can stuff it full of desiccant to help keep your AMS dry

✅ Looks great

Other adapters are:

❌ Too small

❌ Too weak

❌ Too light

❌ Too moist

❌ Too ugly
