This is an alternative and cheaper (for me) solution for a counter weight, and yes I know, “properly tensioned belts you wont need this” which is anecdotal anyways.

I included a picture to what the product looks like in case the links happen to die and you come across this beofre I update with a working link.

BOM:

** I ONLY RECOMMEND FLAT HEAD BOLTS SINCE THERE IS A GROOVE FOR THEM IF YOU DONT CARE ABOUT THAT, THIS https://www.amazon.com/1080pcs-Washers-Assortment-Stainless-Assorted/dp/B0C8TB9FDM/

ASSORTMENT HAS ALL M3/M4 YOU NEED FOR A GOOD PRICE. **

Door closer, price (at the time) $3.02 USD + 1.99 shipping or free if you buy over 10 dollars which I did for other projects, and back up just in case :

UPDATE updated link for aliexpress, I purchased 1100g but 1000g is fine.
