This is my super simple design for a smartphone holder.

I use it to keep my phone in sight when I'm working / gaming / studying on my desk.

It helps because you don't have to pick up your phone. You simply take a quick look to see if the message or whatsoever is important or not. The phone remains in a nice angle to take a quick glance on the screen.

I used 2 M4 threaded bars and 8 M4 nuts to connect the two parts.

My threaded bars are about 5,5 cm long. Works like a charm for an iPhone SE (2020). If your phone is bigger you might have to use longer threaded bars.

Advantages:

• super simple
• not using much filament
• small and effective

Disadvantages:

• no fancy design
• you need threaded bars and nuts (or something similar)
