The Beast: universal cupholder for strollers

The system contains two cupholders:

• The Beast - named after its monstrous appearance, works with a gravity-triggered locking mechanism and lets you hold most sizes of beverage containers (from a very small coffee cup to a large pint of beer)
• The simple one - a very simple cupholder designed for a 0.5l can or similar size.

Both cupholders are attached to the stroller with a quick-swap system - this allows easy upgradability as you may design your cupholder just with screw holes and use my quick-swap system to attach it.

The “stroller frame holder” part is designed for the Kinderkraft Prime Lite 3 stroller. If this part doesn't fit your stroller, you might need to redesign it.

You will need several M3 screws and nuts of various sizes, as well as some springs and a short piece of 8mm aluminum tube. I will update the numbers and lengths of the necessary materials.

Printing setup:

• Print all parts with PETG.
• (Optional) Print “Stroller_frame_holder” and “Cupholder_base” with PC Blend or similar highly resistant material. These are the most stressed parts.
• Set as many perimeters as possible (at least 4) to achieve the highest possible resistance.

Materials:

• M3 screws
• M3 nuts
• M3n Nyloc nuts
• 6 springs
• aluminum or metal tube (8 mm outer diameter, 6 mm inner diameter)
• Superglue
