Update: due to the release of Prusa Slicer 2.6.0 alpha6, I am able to export the stl file without the negative volume.  Stl file added. 

My nephew appreciated all the spare ammo for our 2008 Hasbro Millennium Falcon, but wanted to keep things organized so I came up with a missile storage rack to keep them up and out of the way.  the pegs should press fit into little holes in the underside of the rectenna/jedi training remote/djarek side hull cover. If they don't stay in place, flip them around and try again.  you can also flex the racks a little to make them fit. Mirror the 3mf file to print a symmetrical copy and hold those dangerous ordinance up high where only Chewy can reach them.  

I had to share as a 3mf file because I designed it entirely in prusa slicer 2.6.0 alpha 2.  The negative volumes appear as missiles in the viewer.  Missiles can snap in fully to the holders or they will stay still if only halfway snapped into place. 

I recommend a tough pla filament like inland Tough PLA from Microcenter. I used ‘true red’ Tough PLA for the racks in the photos.  These were printed at default prusa slicer 0.24 DRAFT with a 0.4mm nozzle. 3 perimeters 15% infill.
