Features
- Close fitting lid keeps bugs, sand, and rain from getting into your drink while you recline at the beach.
- Lid springs open at the push of a button.
- Compatible with multiple sizes of rubber bands, which keeps the collar squeezed tight to the can and acts as the lid's spring. The recommended rubber band size is #30 (2" long by 1/8" wide).
- Custom text and logos can easily be added to the large flat surface of the lid.
- Spill-resistant when you add the printed TPU gasket to the lid. See “Download Files” for STL.
Usage Tips
- After snapping the lid into place on your can - squeeze the rear of the collar at the hinge. This insures a snug fit of the collar to the can.
- When your beverage is finished and you wish to remove the PopTop:
Open the PopTop's lid.
Use two hands to gently pry open the hinge at the rear of the collar.
Lift the PopTop off of the can.

Printing Tips
- Due to natural variation in filaments and printers, the paddle's press fit into the collar can sometimes be too loose. If this happens, try reprinting the paddle at 102%.
- Always clean your build plate with water and mild soap.
- Supports must be enabled - The collar and lid designed to be printed with supports.
- Layer Heights - The collar and lid are printed at 0.2mm layer heights, while the paddle/button must be printed at 0.12mm.
- No Brims - Brims are not required for any components.
- Recommended Material - PLA Basic, PLA Matte, and PETG filaments have all been tested successfully.
Assembly
- Remove supports from the collar and lid.
- Press fit the paddle/button into the front of the collar. Gently rock the paddle/button back and forth. It should have slight resistance.
- Gently pry open the rear of the collar and insert the lid's pivot to complete the hinge. Cycle the lid back and forth to insure the lid moves smoothly over the entire range of motion. If needed, shave material with a sharp blade from the pivot pins where there is interference.
- Wrap a rubber band around the two horns on either side of the collar. Stretch one of the lengths of rubber band up over the hook at the rear of the lid. Test the opening force of the rubber band when the PopTop is installed on a can. If more force is required, try a shorter rubber band or double up the rubber band before installing on the horns.
