I designed cup holder for paper coffee cup in two sizes.

The cup can be get on amazon.com. (sorry for Japanese site)

You can find cup size from following figure;

<Model1-5>

<Model6>

If you'd like to modify size, please let me know. I'll share Fusion360 project file.

<Model1>

Firstly, I designed this model with two finger holes. But is was not accepted by my husband due to small finger holes, especially, 2nd hole is tight to his middle finger, so I tried to design that with one hole to make it flexible.

<Model2>

This model has one finger hole and it's not stable supported by one finger.

<Model3>

I don't want bridge below the finger holes, so changed the design. But top of the finger hole is pointed and it is not fit to the thumb to support auxiliary.

<Model5>

I changed the model with two finger holes. I modified the shape of the hole from round design to leaf shape, from the design and less bridge point of view. But it wasn't accepted by my husband also due to the design with point on the top and small hole size.

<Model 4, Model 6, as final design>

I modified model 5 to have round hole. And the modified underside of the lower hole to have curve for the good looking( I think).

Model4 and Model6 are different in size.
