### Printing

- For 3D printing **use the 3mf files**, they are set up for prusa slicer.
- For more info check `Print Settings` section

### See through parts

The visor is a challenging part to make. You have to use vacuum forming to create it. 3D printing even with transparent filament is nowhere near clear enough to be usable. However in the maker community making vacuum formed parts are not unheard of.

In this video http://y2u.be/RNAc0C8nApc you can see great tutorial how visor can be made and colored in a workshop. I decided to 3D print a buck on a large printer and send it to vacuum forming shop. I made an error by not smoothing the buck enough. It truly needs to be smooth like glass. I ended up with 3D printing artifacts pressed into my visor so it is harder to see.

Other option for creating the buck beside 3D printing is to mill the buck from soft wood and polish it.
