Universal XL Stroller Cup & Phone Holder

This is a universal XL cup holder for baby strollers, designed for real-world use — not just coffee cups.
It comfortably holds large bottles up to 2 L, plus includes a phone holder, and an extra modular slot left open for whatever you want to add next.

Mount the Pram_mount to almost any stroller handle using two ZIP ties. For best grip, place a small piece of rubber or leather between the mount and the handle to prevent slipping. Once mounted, the Cup_holder slides on securely.

On top of the cup holder are two slide-in interfaces:

• One side can hold the included phone holder
• The other side is intentionally free — made for your own ideas

To make that easy, a STEP file of the slide-in interface is included. You can:

• Design your own custom add-on
• Merge it with anything directly in your slicer
• Add text, logos, hooks, holders, or… yes, even a Benchy if you feel like it.

The Benchy add-on is included as a fun leftover from the original Makerworld challenge, but the core idea here is simple:
a sturdy, oversized, modular stroller holder that actually fits what people carry.

Practical first. Modular by design.
What you slide into the free slot is entirely up to you.
