Gen 3

  • Snap in Side Labels that are customizable - The text, color, and frame color can all be customized by the user. 
  • Stackable - Chamfer on bottom and mating feature on cover.
  • Customizable Text on Lid
  • Improved Robustness - Wall thickness increased
  • Moved snap lock feature from start to end of the cover groove. This will improve the issue a few folks had with the the seam delaminating between layers. 
  • Simplified Geometry

Assembly

  1. Snap in side labels - Hook one of snap features of the label and slide your finger across to engage the other snap feature. 
  2. Snap in Round divider Tray  - It you need to remove this just use a pencil and gently pry it to disengage the snap feature.
  3. Slide Cover on - The first few snaps will be a little firm, but it will loosen after a few and it sits for couple days.
