Stackable Laundry Detergent Cup (Wash & Dry Safe)

This is a stackable measuring cup designed for liquid laundry detergent. The goal was to make something simple, durable, and easy to store without the usual pile of detergent caps cluttering the laundry shelf.

Each cup nests cleanly into the next, allowing multiple cups to stack vertically without sticking together. This makes it easy to print several and keep extras on hand for different detergents, stain treatments, or laundry areas.

The design features:

• Flat base for stability on washers, shelves, or countertops
• Smooth interior walls for easy pouring and cleaning
• Stacking lip so cups align neatly without binding together

I printed these in ABS, which handles hot water, detergent exposure, and dryer heat much better than PLA. That means if the cup accidentally ends up in the wash or dryer, it’s far less likely to deform. We personally drop our cups into the wash to be rinsed out during the cycle, and often they end up going through the dry cycle (though hopefully the red will be a flag to pull it out now!). 

The model is intentionally simple and prints quickly, making it ideal for batch printing if you want several stacked in your laundry cabinet.

To Print Multiple cups, Ctrl + A to select all three objects, and then clone them the desired amount, try not to move any of the pieces around, or you'll throw off the print. If you for some reason want to spread them out, make sure you select all three parts for that individual cup, because when i tried merging them, it printed a really big base, and the cup was hollow but had a top to it, instead of the negative modifiers just doing what they were supposed to.
