When you're relaxing in a lazy arm chair or your favourite camping chair, do you ever try to balance your phone or tablet in the cup holder?

With this customisable 3D printable design, you can turn any cup holder into a sturdy stand for your device! When was the last time you actually put a cup in a cup holder anyway?

This fully customisable design can be adjusted for cup holders and devices of any size. Create stands that are solid or hollowed out for storage, and use the built-in preview tools to visualise your device to check it'll be well balanced in the stand.

This design is completely free and shared under a permissive license. Your support is hugely appreciated.

How to customize

For the best experience we recommend customizing this design in OpenSCAD.

The basic steps are as follows:

1. Measure the thickness, height and width of your device and enter the measurements as values for the Device_Thickness, Device_Height and Device_Width options. If unsure, round up rather than down.
2. Measure the depth and diameter (at the top and bottom) of your cup holder and enter the measurements as values for the Cup_Holder_Insert_Diameter_Upper, Cup_Holder_Insert_Diameter_Lower and Cup_Holder_Insert_Depth options. If unsure, round down rather than up.

1. Use the visual aids to check the position of your device. For the best stability, the center of your device (signified by a red sphere in OpenSCAD's preview mode) should be on or slightly forward of the Z axis (vertical) center line. If it's not, increase the Grip_Offset_Percent and/or decrease the Grip_Angle values accordingly.
2. Decide if you would like the holder to be hollow and set the Hollow value accordingly. Hollow stands require slightly less printed material and the hollowed out section can be used to store small items, such as in-ear headphones or portable power banks. Depending on the position of the charger port of your device, the hollow section may also allow you to charge your device when it is sat in the stand.

There are a number of other options that haven't been covered here. You can experiment with them to create a design that suits your needs and tastes.
