We spent the last few months designing a hands-free paint shaker (3500 RPM / Vortex motion).
Hey everyone,
If you’ve ever pulled out a bottle of metallic paint or thick primer that’s been sitting on a shelf for a few months, you know the pain. You end up with a solid brick of pigment packed into the bottom, and no amount of hand-shaking seems to actually mix it properly.
When we started working on VOORTEX, the main goal was simple: we wanted something you could just drop a bottle into, hit start, and go back to masking, cutting sprues, or prepping parts while it does its thing in the background.
A few specific annoyances we tried to solve during development:
First was the mixing action itself.
Standard vibration works fine for light acrylics, but for stubborn, separated pigments, we opted for a high-speed spinning motion (up to 3,500 RPM). That creates a vortex inside the bottle that pulls the settled sludge from the bottom up through the liquid.
Second and probably the most annoying thing with high-speed mixers—was "desk walking."
At 3,500 RPM, if the dampening isn't right, the machine slowly migrates across your cutting mat or shakes your entire hollow desk. We ended up designing a dual-layer internal cushioning setup paired with silicone feet underneath to isolate the vibration so it stays firmly in place.
We also went with a stepped, flexible holder instead of a fixed clamp.
As long as the bottle is roughly between 25–50mm wide and 10–60ml, it automatically centers and locks in, whether it's a dropper bottle, a glass jar, or a standard acrylic container. Added a 0–3 minute timer display on the side as well, just so you can set a repeat routine for paints you use constantly without guessing.
Basically, it's meant to save your wrist on those stubborn, heavily separated paints and keeping your hands free while building.
We’re really curious to hear how everyone here handles paint prep.
Do you stick to wrist power, agitator balls, standard vortex mixers, or something else entirely? And if you already use a shaker, what’s the one thing that annoys you most about your current setup?
