Single & Dual paint brush cleaner

thingiverse

I designed a better brush cleaner to replace a sour cream container. My initial version featured a single water well, but I soon realized I didn't want two separate wells for dirty and clean water. To solve this issue, I merged the wells into one unit connected by a brush holder ring. Initially, I planned to add a grid at the bottom of the cleaner to allow users to scrub their brushes against it. However, this design would have made cleaning out settled paint from the grid extremely difficult. Instead, I opted for rings with 2mm widths and 3mm spacings, which works efficiently and is easy to clean using a bottle brush if needed. I printed my cleaner using PETG filament, allowing me to safely use hot water without compromising its structure. If you plan to use this cleaner for substances other than acrylic paint, I recommend printing it with chemical-resistant filament to ensure durability. The smaller clean water well size makes sense, as once most of the paint is removed from the brush, the clean/rinse water doesn't become dirty quickly. To account for printer variability, I created two versions of the clean water well: one 1mm smaller in diameter than the standard design. This modification addressed issues with the half-moon points being too long on some prints.
