all of these parts are designed specifically for the Olight i1R2 Pro key ring torch \ flashlight.
you can probably make them fit any other torch by scaling them up \ down appropriately.

best results for the lightsaber blade part is 2 walls max, zero infill, zero bottom layers and use a raft for adhesion.
all other parts can be printed solid or with your preferred infill.
you may need to slightly scale up or down the model size depending on your printer settings and how tight\loose you want them to fit together.
if you get it right it will be a snug press fit.
i may add more designs for the hilts in future, and if you design your own let me know!
