The Goose Gear 2007-2018 JKU Cubbies are designed to have the seatbelt covers fill a hole by the roll bar where, however if you remove your rear seats and the seatbelts then you don't have a cover to fill the opening. For some reason they make a version for the JK without seatbelts but they don't offer that option for the JKU so I needed to design something.

This design give you a good looking cover that can be easily removed depending upon how you attach it. I secured them to the cubbies using three strips of velcro (only one is visible in the photo), but you could probably drill holes and secure it with screws. Glue would also work, but removing it would be problematic.

I printed these in carbon fiber with 30% infill, but PLA or PTEG should work fine too. If you wanted a quicker print you could probably get away with 10% infill, but be careful what you put on them.
