Lightsaber - translucent modular blade

I designed this lightsaber for my son, he is having a lot of fun with it. It is modular, each module is 170 mm in length. You can print it longer or shorter, just add another module. It is designed for Convoy S2+ torch, but you can fit any torch with outside diameter of max. 24.5 mm and 117 mm length.

 

Printing:
I printed the hilt with black PETG, with adaptive layer height. Bottom and top threads should be printed with 0.16 layer to work correctly, the rest can be printed with 0.28. PLA will work no problem.
For the blade I used Rosa3D red translucent PETG. You can use any translucent filament, I tested regular white PETG as well and it also lets a lot of light out. Threads should be printed with 0.16 layer, the rest can be printed with 0.28.

 

Infill and walls:
Infill pattern is clearly visible when the torch is on so it is something to consider. Less infill means more light out, but the parts get weaker. Grid pattern and gyroid look the best in my opinion, not a lot of infill is needed, just couple percent. You can look at it in slicer and choose your preference. I tested single wall without infill, this looks amazing, but is really just for looks, not for children toy - it's too delicate. Single wall with infill is a little better, but the wall breaks easily. Two walls with couple percent of infill is the best in my opinion.

 

Torch heat:

Convoy S2+ is a really powerful torch and produces a lot of heat. When enclosed in the hilt it cannot cool itself when the highest mode is selected. You can damage your torch and/or the battery, so this is something to consider when you give this to your child.
