Craftsman Rolling Tool Cart Caster Mount
This is a replacement caster mount for a Craftsman rolling tool cart. The original (black plastic Christmas tree) style is notorious for breaking, causing the wheel to fall off while moving it, especially over bumps. I was looking to order a replacement and saw a review from "teddy1245" on the Sears website, which referred me to a better part from a similar tool cart. I went to order one ($4), but shipping was $8... no way I was going to pay $12 for this piece without a fight, so I made one.
According to the website, my tool cart is item # 00959355000P, and model # 59355 or 50259355. The cart had an original part # GLP057445. The upgrade part (which I based my design on) is 9N012L-5, from the service cart model # 87559691.
It was a quick print (45 minutes with 100% infill), the part feels solid (I used ABS), and the wheel doesn't fall off. Success!
