A parametric, multi-angle, minimalist phone/tablet stand.

I've attached the FreeCAD file and a bunch of pre-configured STLs.

There's also a FreeCAD file for a "convex" version. This was my initial idea, but after a bunch of iterations I much prefer the concave version.

The only STL I've printed is the main file - please report issues if you try one of the others!

Print Settings

No special settings needed unless you go nuts with the angles. I printed in regular PLA with my functional part settings (CHEP's "Extra Fast" profile):

• 0.4mm nozzle
• 0.28mm layers

Model

In the FreeCAD model, open the "Values" spreadsheet and update "Input Values" column to fit your needs. That's it!

I've dabbled in F360, but this is my first FreeCAD model. The model is fully constrained, but things still get weird on occasion when input values change. I'd love some feedback to improve the model.

Design

I originally threw together a four-angle, custom-thickness remix of Smartphone Holder / Stand with Multiple Angles by MetaSeb in TinkerCAD two-plus years ago and have been using it daily. I've come across two issues:

• Determining which angle is which is annoying.
• I only ever used three of the angles, and only two regularly.

I decided to redesign it from the ground up with some goals in mind:

• Parametric design for a perfect fit per device
• As small as possible while maintaining stability
• Able to orient it at a glance
