I printed the original model on my Prusa Mini+ but I had to scale it down because the model is too high. When it was finished the model was too small to fit a headset on it.
To solve this problem, I used this drawer + enclosure model from thingiverse: https://www.thingiverse.com/thing:1046664 and glued it underneath. Now the model is higher and it works!
You'll still need to add supports to the model. Take a look at the 2nd picture to see my supports.
I used OpenSCAD and changed some settings so it would fit the box. If you are going to print the headset holder a bit bigger, you will have to tweak the settings to make it fit.
The author remixed this model.
