I made this using Infinati's Luke ROTJ Lightsaber design! I had the idea for a pixelized one, and so used 3D slash to do this. It was very simply done. Please be sure to check out Infinati's Lightsaber with the link below!
This is a good model based on a simple idea! Also, 3D Slash shows to be an effective tool for people who want to do simpler modeling, or 8-Bit/Pixel modeling. And, if you get too big with cubic detail, then you can always scale down a model!
I hope you enjoy!
Solid or Sparse - Doesn't Matter
Supports are minimal!
I do not think that this has to be exactly as shown, as infills can be Solid, Sparse, or perhaps other (custom). Just be sure to have supports, and they'll be minimal, anyway!
I designed this in the 3D slash customizer provided by Thingiverse! Additionally, I added a mark on the bottom.... Enjoy!
