We had a manky old metal metal scrub brush/sponge caddy, and it was time to toss it. So I modeled up a replacement to fit our usage case. Treated it with Art Resin to avoid any possible issues with mold over time, would recommend doing so if your use would get it contaminated with food particles or submerged in water over time. Haven't seen a single issue since making it, and I've been using it for more than a month so far. Designed it to fit medium sized suction cups-- purchased some on Amazon but also fits common medium sizes from hardware stores. Printed in PLA as our sink is deep enough that hot water/steam never really touches it, but if you're going to have it in contact with considerable heat, you could run into issues with deformation. If looking at higher-temp materials, be careful to use food-safe options. Thanks for looking and have a nice day!
