Designed this to display a lightsaber built at Savi's workshop. The lightsaber slides down the center and is largely supported by the base. I used 2 5lb(Large) command strips for each part (possibly overkill but sits more flush with the wall) and designed a small gap on the bottom of each part. The gap should allow tweezers/pliers to be used to pull the command strips for removal and otherwise keep them relatively hidden. 

I printed this originally on an UP! Mini 2, with better results on a Flashforge Adventurer 5M Pro. Filament used was Inland Gray PLA+. Settings were the stock PLA settings for each printer respectively.

I have uploaded the stl and f3d file for the blank version, for the photos I added the Jedi crest from:

I have also used other symbols for friends and family:

Adding the symbols was a nice easy challenge in Fusion 360 to get a little better at working with it.
