Cup Turner with Epoxy Kit for DIY Tumblers

The Cup Turner with Epoxy Kit for DIY Tumblers spins tumblers at a steady speed while epoxy cures, giving you smooth, drip-free finishes without the lumps that come from hand-rolling.

The motor holds a slow, even rotation so resin self-levels across the cup. The included epoxy kit means you can plug it in, mount your first tumbler, and start a project the same day instead of hunting for compatible parts.

Why this cup turner works

• Even rotation: the motor keeps a steady speed so epoxy spreads flat instead of pooling on one side.
• Epoxy kit included: ships with resin and hardener so you can start your first tumbler the same day.
• Adjustable cup mount: fits skinny tumblers, fat tumblers, mugs, and pens with a few tweaks.
• Lightweight base: easy to set up on a craft table and store on a shelf between projects.
• Smooth finish: consistent spin avoids the fingerprints and bumps you get when rolling cups by hand.
• Beginner friendly: plug-and-go setup with no programming or app pairing required.

Frequently asked questions

How long does a tumbler need to spin?
Most epoxy formulas need 6 to 12 hours of continuous rotation to cure smooth. The turner runs unattended once you mount the cup and start the motor.

What sizes of cups fit on it?
The adjustable mount fits skinny 20 oz tumblers, fat 30 oz tumblers, standard mugs, and even pen blanks if you swap to the appropriate chuck.

Can I use it with my own epoxy?
Yes. The turner works with any standard 1:1 tumbler epoxy. The included resin is a starter so you can practice before buying a brand you prefer.

Is it safe to leave running overnight?
The motor is rated for the long cure times that tumbler resin needs. Place the turner on a flat, well-ventilated surface and check it once before bed.
