Dish Washer Wheel Plug

thingiverse

I recently acquired a thermal imaging camera and discovered that the reason these plugs were coming loose was due to water temperatures reaching nearly 140°F or 60°C, plus whatever temperature is reached during the heating/drying cycle. If replacements fail as well, I will explore printing with high-temperature materials. I've purchased replacement wheels from Amazon and left the files up for anyone who wants to remix them, but I'm abandoning this project. After several uses at high temperatures and heat cycles, they started falling out again. I've changed this to a work-in-progress and am currently experimenting with other materials and newer designs. These small plugs that hold the wheels to the bottom rack of my KitchenAid dishwasher fell out around the same time within a week of each other. The dishwasher was fairly new, so it makes me suspect that it could have been planned obsolescence on their part. I quickly sketched this in Solidworks and printed a few test prints in PLA for size fitting and modified the model until I got it just right. These new plugs are designed to be slightly oversized at the end to prevent them from coming out easily. It was printed using PETG, meaning it should be able to withstand the high temperatures that should be expected inside the dishwasher during the drying cycle. The ones on the rack currently have survived a few rounds in the washer so I am confident that they should last for a while. A full set of these plugs would be 8 pieces. Thanks!
