heavy duty key chain

This text showcases my third keychain design, which after months of use still looks great. It is assembled with four 3mm x 13 bolts and nuts, featuring spacers at bolt locations without keys to prevent flexing. This model can hold up to four keys; however, the height of the spacers can be adjusted for additional or fewer keys as desired. While there are numerous similar designs on Thingiverse, this is my unique take on a practical and durable keychain.
