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"](https://thangs.com/designer/CHEP/3d-model/Updated%20V3%20Cura%20V5.0%20%20Filament%20Friday%20ExtraFast%20%280.28%29%20Profile-913959) 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](https://www.thingiverse.com/thing:4702756) by [MetaSeb](https://www.thingiverse.com/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

Parametric Device Stand

> Employees Must Carve Slayer Into Forearm Before Returning To Work

Ensure work-from-home employees are following proper safety and sanitary protocols with this two-tone plaque.

To slice:
- Import both models upside-down
- Center the models together (overlapping)
- Delete the base plate model and export
- Undo
- Delete the text model and export

Print the text in accent color. Do not remove the model from the bed (remove skirt if using). Change filament to base color and print the base plate model.

osha-slayer-words.stl

Custom bracket to mount a microphone to the bottom of an Acer Predator XB271HU bmiprz monitor via 5/8"-27 threads.

**Design**

I designed this specifically to mount a JLab Talk Go mic, but the standard threads should support anything that isn't too heavy. It slides in from the sides (v1 could clip in; v2 cannot).
The design leverages the front bevel as well as the back ridges in order to stay place. The fit is pretty exact on my uncalibrated printer.

**Print settings**

I printed this on an Ender 3 V2 in PLA using a 0.4mm nozzle and 0.2mm layer height. YMMV on the threads - may need thinner layers.

Nozzle: 0.4mm
Layer height: 0.2mm
Supports: No

**Updates**

2021/12/31 - The part bent under stress after about six weeks and would no longer stay attached. New version attempts to solve this by thickening the part and removing perpendicular stress points. New version is now symmetrical to be more versatile and remove the need for supports.
