Simple easy chain 25 x 15MM x 3.2mm, 9KG break

I wasn't satisfied with the other chain link designs, so I created a new one that addresses several issues with existing options. Print-in-place chains require too much brim material to be reliable for small-scale projects, wasting resources and taking up to 10 times as long to clean up as assembling links individually. They also have layer weaknesses. Chains with good assembly mechanisms after printing individual links are often too large and can't scale down small enough, or they lack a clipping mechanism altogether, necessitating excessive material usage. This chain link aims to solve these problems by being only 25mm long per link. Assuming your printer is accurate, it features a tiny yet strong clip for easy assembly. I specifically designed this chain for use with a 0.4mm nozzle and 0.2mm layer height. While other nozzles and layer heights may work, I recommend scaling up the design unless you're using a 250% or higher scale factor. For example, if your nozzle is 0.6mm, multiply it by 250 to get a minimum 150% scale. No supports should be needed unless printing at 250% scale or above.
