Wheelchair Cupholder with Phone & Pen Holder

This is a versatile, 3D-printed cupholder designed to attach to a wheelchair or any vertical tube up to 24mm in diameter. It securely holds a drink and features built-in slots for a phone and a pen. I designed this to be a simple, practical accessory that can be useful for all sorts of things, not just wheelchairs! It's sized to fit a standard Yeti-style 30-ounce insulated tumbler.

Printing & Installation

• Print Settings: I printed mine with PLA using the default Bambu Studio settings. The result feels quite sturdy, but I'll update the description with any long-term use notes.
• Mounting: You can easily attach the cupholder using adjustable nylon cable straps or standard zip ties. The straps I used are similar to these from Amazon: https://amzn.to/46i4s5s.

I hope you find this as useful as I do. This is my first time sharing a design on MakerWorld, and I'm excited to see what others think!
