This insert holds 10 fully-assembled dials just perfectly so that the lid can close and the dials stay put. You can stack them side by side and even put them in the end areas where one of the corners is more rounded! The holes on the bottom allow you to put it in multiple positions, not just in between the wall guides that are built into the container. You can even fit the insertable walls that come with the container on either side if you want. Peek over the top to just barely read the ship chassis name on each dial. No need to pull them all out to see which one it is.
This only fits inside the large compartment of the Plano 3750.
In the listing images, I used a grey filament only used for prototyping, but you can view all of the available colors on the colors page.
