Bolt&Nut for Ultimate drawer System

I needed bolts and nuts to put together several modules of the "Ultimate Drawer System" design https://www.thingiverse.com/thing:2302575, but did not have the right sizes, so I found this customizable parts https://www.thingiverse.com/thing:193647 and printed them.

I did several tests to get the right sizes, so I thought to save you the time by uploading directly the STLs for 1 bolt and 1 nut.
The bolt has a slot drive type

The parts should fit well depending on the tolerance of your printer, but you might want to scale to 102-103% the bolt model in the slicer for better fit.

Printing:

As the parts are really small, is better to print slowly (20mm/s) to allow the layers to cooldown, and print more parts a bit apart on the plate for the same reason
