Universal add-a-cupholder. Fits everything!

General:

A highly adaptable cup/can-holder for everything from soda(pop) cans to Nalgene bottles.

Clamp is adjustable in 6mm(.25") increments to fit most cars/trucks

Why I designed this:

1. I love Nalgene water bottles, but I hate having them roll around in my car because they don't fit in the cupholder. 
2. My cup-holders usually become a repository for all the odds and ends I use daily in my car, to the unending annoyance of my wife when she rides with me. 
3. My wife also regularly has more than two cup-shaped items in her own car.

Printing notes:

Layer height: Works great at any height

Recommended Material: PLA or better

Supports: Under the “cupholder” horizontal shaft only. I designed it so messy support interfaces won't interfere with the adjustment features.

Infill: 15% Gyroid or triangle

Walls: 4

Other Modifiers: Print as oriented

Material Quantity: ≈98grams with proper support

Development notes:

I tested initially in Sunlu PLA 2.0+ on Centauri Carbon at .2 layer height with 15% gyroid infill and 4 walls. This worked surprisingly well for a bench test, and the flex was impressive. DO NOT print from PLA unless your car stays cool year-round. It will melt.

My functional model was printed using Priline PC at .16LH, but would work well from ASA, ABS, or likely PETG too. 

PC is excellent for this application if your printer can handle it, but I recommend against CF filled because this design relies on good layer adhesion, and CF fill reduces this property.

I've included a printable retaining pin, but a 4mm X 30mm bolt is ideal if you have one available.
