Remix to hold a piece of 1.75mm filament as the lightsaber.
The original piece was very big to be considered a "mini".
This height of my model is 7cm.
I advice not to shrink it further down (or enlarge it a lot) if you want to use the filament as the lightsaber.
Note: The red filament lightsaber is not printed. ;)
Edit 3-8-2019: Fixed a few errors and little flaws with Meshmixer
minimum support is needed. Please check your slicer if you are comfortable with your slicers settings.
When printing with support, I advice to use at lease a smal brim.
