Bambu Spool Weight - Heavy Duty

Bambu spool weight for AMS. I have seen lots of spool weights with batteries in them and I just did not like the idea of using batteries. I creates one that takes a 500g scale calibration weight (measuring 38mm x 62.5mm) that I purchased on Amazon that I can use over and over and not worry about battery corrosion or leakage: https://www.amazon.com/dp/B0C6KLKB21?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_2 . You can go with a smaller calibration weight or add anything you want (as long as it is smaller than the above mentioned measurements, the print is solid adding a little weight itself.
