*EDIT* Jammed fairy leds into the openings under the lenses, looks better in person but I tried to take a photo ^ I got inspired by the little handgun business card holders and wanted to make something to share for May the 4th and came up with this.
if you just load the Bambu 3mf and slice it modifies the saber to hold cards and the blades will press fit slide in.
if you load the generic 3mf you will have to tack on the center blade with a little dab of glue etc. OR. don't add the blades! :D
Enjoy, I hope someone makes more versions (sabers) ;)
