Gridfinity Customizable Divider Bins - Enhanced

Based on Gridfinity Customizable Container by jrouvier2

The original SCAD file did not allow for customization of the following due to true/false issues with Customizer:
- Label
- Finger slide
- Magnets

I have fixed the SCAD to enable these fields.
1 = True
2 = False

You can now enable and disable these features of the Gridfinity bin.

I hope others find this useful as well.

STLs are provided as examples only. Open the customizer to create your own custom bins.

- Holes for magnets are optional
- The shelf for a label is optional
- The finger slide at the bottom is optional
- Magnet holes end in a cone, reduci
