I wanted to share the modified parts I used by CaseStudyno8 to make a more accurate-looking Qui-Gon lightsaber in addition to making some parts cleaner to print. The original model's outer handle was too tall by a few mm's to print on my printer, so while tweaking that, I went around and changed some other items. Here's a quick breakdown:

-Outer Handle - changed to 4 cutouts, rounded lower corners, and shortened to fit printer (use supports)
-Handle - curved ridges, shortened to fit new Outer Handle
-On/Off button - added knurling
-On/Off Shroud - added slight lip to raise the button to look press-able (use supports)
-Emitter Alt 2 - added an emitter with a simple hole opening for an alternate look.
-Emitter Bottom Black - added thin black disc that goes immediately below the emitter as an alternative.
-Middle Chamber Spindle and Sections - Uses a spindle with 5 sections as an alternative to removing supports from a solid piece.
-Upper Chamber Spindle and Sections - Uses a spindle with 2 sections, reshaped the chamber slightly to balance the overall width.
-Black Button Outer/Inner - Added a screw for a different look.

The pommel is unaltered.
