Full size Kryptonite Sword prop, printable in parts (PETG recommended)
Additional hardware for a full build with electronics:
- Six M5 grub screws
- WS2812B LED strip (144/m)
- Two short WS2812B LED strips with 60/m density for the status lights
- 18650 LiIon battery with protection circuit
- Adafruit Trinket 3.3V
- 12mm rotary encoder (short shaft) with a switch
- 3 resistors (10kΩ - 100kΩ, exact resistance doesn't matter)
- A reed switch (optional)
- One nut and bolt (M4 thread or smaller)
- Epoxy glue
- Black & Silver spray paints

If people print this and want to build the electronics too, I'll consider publishing the schematic (it's relatively simple) and the Arduino source.
If you read the forum thread, you'll find that there are quite a few more models to complete this as full cosplay, which I may make available, if there's enough interest.
The S logo SVG file is originally from Wikimedia Commons, where it is labeled as being in public domain.
The entire sword except for the battery terminals was printed using PETG. The tall parts except for the electronics housing were all printed upright, which means very good interlayer adhesion is required (PETG is great for that). Also, the printer should be able to print at least 180mm high.
The blade segments (green PETG) are printed in single outline vase mode with no bottom or top fill. A skirt/brim is recommended to prevent the piece from falling over during the print.
The guard and electronics compartment should be printed for high strength, so at least 3 shells and 30% or more infill.
Spine1 should be printed three times (flat on the bed).
The battery terminals were printed using a semi-flexible material, but softer is better. If you can't print flexibles and want to build the electronics, you can improvise or try a slightly flexible material like PETG and melt it to fit your battery.
Glue is only needed to attach the tiny filler bit to the electronics compartment and to attach the electronics compartment to the guard. If you just want to display the prop and not wave it around too much, you can skip the glue.
