Took the kids to Disney over February vacation, and went to Savi’s Workshop, and they got to build lightsabers there. Since these are 'spensive and not toys, wanted to make some wall mounts for them for display. Used 1/8" cast acrylic (and backed with .010" styrene sheets - hand cut). Download link is in the video description for the SVG file.
The lightsabers are 3lb each, and via Weld On #4 and some super glue, they hold the weight very well. No failures yet
