Who doesn’t like micro-projects? I am in the process of finishing my last degree – the bachelor in technical physics. During my time on working on my thesis, while I was desperately searching for a new smartphone cover for my S21 on Amazon, I had the idea to combine a magnetic smartphone cover, a neodymium magnet and the holder spot of my old car into something handy!

So I ordered the stuff (https://www.amazon.de/dp/B09D388G35?psc=1&ref=ppx_yo2ov_dt_b_product_details & https://www.amazon.de/dp/B0BCQHQSZD?ref=ppx_yo2ov_dt_b_product_details&th=1) and went on to tinkering during a writing break!

I only needed one neodymium magnet, one scew which fitted and I took down the old holder of the car. It was broken, so I used some instant glue. With a 3D printer, I could have printed the black part. Due to not having a lathe, I had to file the screw to my needs 😂!

After some filing I quickly put those together and mounted them on the car holder:

 

I tried to add the phone with the case, but it seems that the neodymium was too strong!

Seems like the threaded sleeve broke out of the already damaged plastic!

The solution was to use a longer screw and a nut, simple as that:

With that, it worked! I tested it already for tracks with ~40km. Yeah!

In my opinion, the perfect micro-project! Refreshing for in between. And hopefully soon, physics will be finished and the game projects will continue. Which micro-project will be YOUR next one?
