The Lego  Dune Looks great on the wall, But it looks even better when it's hung at an angle. Unfortunately most wall mounts only allow straight up and down. 

This mount can support any angle (you could probably even mount to a go pro) and the model won't separate. There are three different mounting spots for a positive connection with your model.

1. Like other mounts it attached to the landing gear. 
2. The studs on the top connect to the plates below the landing gear knob.
3. Holes for studs that connect to the main frame. 

The third connection is options ensures the model can't come loose if the landing gear comes loose. 

Due to the studs on the top , you'll need to loose the landing gear a little to slide the model onto the mount, then secure the landing gear.
