Subnautica Thermoblade

Use modification station on your survival knife, along with 1 unit of silicone rubber and 1 unit of titanium.

But seriously...

3mf file contains blade cut in half, with 4 parts that you can change colors, print and glue together.

If you want to have proper survival knife with LEDs there's space in the model, change the red parts to something transparent, and insert LEDs, place for a switch at the bottom. - reused thingiverse model updated with AMS, fixed stl, and sliced for P1S. Enjoy

______ original notes: 

This is the glowing knife from Subnautica called Thermoblade. It is printed in 7 pieces to make it as perfect as possible.

This knife can be printed to be either with LED or without. The leds used is 0805 SMD led's soldered to think wires. The whole circuit uses a ATTINY85 as a brain to get the breathing effect. This is very difficult as this is very tiny components and not that much space. But you can head over to my instagram /kjetilh4 and see the result there.

If you just want the knife without the hazzle of adding LED's just print the clear parts with red PLA. I guess that will look really good too.
