Chain tensioner V2
thingiverse
Chain tensioner with bearing has been thoroughly tested on a 9-speed chain, but I'm unsure if other chains will fit properly. A 3mm axle is required (must be cut down to 16 mm) and can be sourced from the following website: https://fr.aliexpress.com/item/32967805012.html?spm=a2g0s.9042311.0.0.27426c37Q8ooI6 Additionally, mr63zz 3x6x2.5 bearings are necessary and can be obtained at this link: https://fr.aliexpress.com/item/32962032067.html?spm=a2g0s.8937460.0.0.27002e0eaNKFKe
