Xia Cargo Tray Spacer (slim)

@Fabmaszter's fab Xia insert is great - but my Ship Mats from the base game are each around 1mm thick, and it struck me that the cargo spacer part could be thinner, and allow me to stack the Ship Mats on top of the damage/token tray, making the entire insert more compact and shake-proof. 

Without making the damage tray wider, an extra tray is required to make everything snug and secure - I used this to store some pens, extra dice and expansion tokens.

I strongly recommend my remix of @Corey's Missing Spacer to raise the Tier 1 ship holder up to the same level as the other insert components. 

Modified the cargo spacer tray to be a single level, allowing the ship mats to be stacked above. Added an extra spacer/tray for miscellaneous components, and keep the damage tray secure.
