While I'm 3D Modeling mechanical parts (with bolts in it) I really like to have the bolts in my hand to get a better idea of scale. This is why I designed this bolts holder with various bolts in it!

I made a full 3D Modeling, 3D Printing, DIY video about this project:

I made it so you can choose between the standing angle of 40° and 50°:

You can put in 2 NFC chips (on both sides) to store data.

For assembling the bolt holder you need these bolts and nuts:
- 4x DIN439 M4 Nuts (they're lower)
- 2x DIN7991 M4x16 Bolts
- 2x DIN7991 M4x20 Bolts
