Parametric USB Organizer with screw holes (on the back) to mount it on a wall.

There are many models for USB holders/organizers in Thingiverse but all I cound find were in one row so I made a model with OpenSCAD and decided to share it here. This model is suitable for wall mounting.

This model is a customizable model, you can use Thingiverse Customizer to customize. Body:

• number of rows
• number of columns
• spacing between the holes
• corner radius

Screw holes (on the back)

• diameter of the screw head
• diameter of the screw shank/threat
• height of the screw head
• tolerance of the screw head hole.

Connector

• size of the connector (the defaults are for USB A)
• tolerance of the connector hole which you can tweak so the holes aren't too tight.
  I have used 0.3mm which gives a snug fit.
  Please note - if your printer is not calibrated you should use something like 0.5.
  The tolerance can also be filament brand/type dependent due to shrinkage. So test it with a small piece before you print a large one.
