Design principles

• This USB holder can be joined with another unit by snap-fit mechanism.
• There are hundreds of USB holder models available, but I didn't want to make 10 slots while I needed only 2 or 3.
• I hate support structures so I avoided any overhang larger than 45 degrees. You don't have to print any support structures.

How to Use

• To connect the units, just push them until it clicks.
• You can disconnect units by one of the following methods:
  • Pinch the side walls(the roots of snap-fit hooks) firmly
  • Twist them slightly while pulling one from the other
  • Push the hooks directly through the hole on the side walls. You may use 1.75mm filament pieces.
