One of my favorite sabers belongs to Luke Skywalker, and CaseStudyno8's design is very satisfying. I noticed while browsing online that there were some variations in the saber so I wanted to make a slightly alternate version. I think it would go well with the TLJ emitter remix by timmy_d3 here: https://www.thingiverse.com/thing:3650143.

Grip

Basically the grip's ridges are uniform to look like a common design variation. It is separated into discs (need 9) and spacers (need 8) thanks to designer vhensler so they can be easily colored by filament choice or painting.
Tips: When printing the segments, ensure your extrusion flow is not too high that your top surface isn't smooth. Print a test disc to check and lower the flow by 2% if needed to get it smooth. Glue segments together patiently using a thin ring of glue closest to the spindle and not too much so it doesn't ooze out the sides (keep paper towel ready to wipe away fast if that happens), and squeeze the parts together tightly for at least 30 seconds to avoid visible gaps. Allow to dry enough before proceeding to the next segment.

Ring

I kept seeing a version of the triangle ring that was a bit pointy so here's that.

Box

To look like some variants, I shortened the control box (filename Switch_Lower) from the hilt a slight amount and added a little embossed panel. Use support.

Personally, I also scaled up to 105% to bring it closer to Obi-Wan's size since it was based on his, plus they look better standing next to each other that way.
