11/20/2016 Still Not Working Right, Redesign Underway. Hand-powered air or water pump designed specifically to fill balloons with air. The lid will pop onto the body and seal securely. The flapper valve and balloon valve pop into the lid as well. Balloons fit snugly onto the nozzle. Please share your prints! 7/22/16 - A design flaw was discovered, a fix is being implemented shortly. (A second flapper valve is needed.) 7/24/16 - REV B: An internal valve has been added to keep air in the balloon during the stoke. Four items need to be printed: Body: TPU or NINJA material Flapper: TPU or NINJA material (NINJA recommended) Balloon Flapper: TPU or NINJA material (NINJA recommended) Lid: PLA or ABS material This design is intended to be printed with a 0.2mm layer height.
