Customizable SUP pump adapter (e.g. exercise ball)

Stand-Up Paddle Board Pump Adapter for Exercise Balls (Customizable OpenSCAD Model)

Overview:
This is a simple and reliable adapter that allows you to inflate an exercise ball using a stand-up paddle (SUP) board pump. I designed it because my exercise ball didn’t come with a compatible pump — and the SUP pump was the only one I had on hand.

Printing Notes:

• Supports: Not required
• Material: Printed successfully with Jayo PETG on generic settings
• Print Quality: Good results with standard 0.2 mm layer height

Design Notes:
The model is built in OpenSCAD, so you can easily adjust tolerances, diameters, or lengths to match your specific pump or ball. It’s a quick, functional print that solves an everyday problem with minimal material.
