This is a combination and remix of multiple excellent projects here in Thingiverse with some improvements by me:
- The original model is Tony Stark's Arc Reactor made by Skimbal.
- For some parts I used SgtMunger edits.
- Note that his design moves the LEDs on the crystal ring between the coils, so they will be brighter compared to the original design that hides them under the coils. You may want to consider printing the crystal ring with more horizontal layers to diffuse the light of the LEDs.
- The cap I designed (see the
arc-cap_with_holes.stl file) is based on the Arc Rector Cap designed by drandolph, however my version has more space for electronics, and also has a central hole for the cables.
- I customized the support cage (see the
- Enlarged the holes on the bottom to make it easier to mount the LEDs. With this change you can push the LEDs from the bottom deeper into the support cage, but they will not fall through (you can use glue from the bottom to keep them in place). With this the top of the LEDs will end within the body of the main crystal which will diffuse their light.
- Added holes on the "arms" to hide the wires that go from the crystal ring to the electronics in the cap.
- Added extra holes on the bottom to lead wires to the cap.
- The bezel is designed by me, based on the one I made for zMark's reactor
- I used the stand designed by LeHof, though it needed some rasping after printing, to make it work together with the bezel.
- I had to repair some of the models to make them printable, and I uploaded the repaired files here.

Credits and huge thanks to the original authors!
I used M3×20 bolts to screw the three inner parts to each other. After that the inner part will tight fit into the outer ring. You may want to use glue or double sided tape to ensure it never falls out.
Electronics, wiring and software
The electronics and the Arduino code was designed and implemented by Peter Takacs, and he made the code and the wiring scheme available for download on Github.
Big thanks to Peter for joining to this project!
Most parts can be printed without any rafts or supports.
I printed the
2_caps (designed by SgtMunger) using rafts and supports, to make sure they stick to the print bed. Printing two at once minimized the risks.
SgtMunger's Updated_Crystal_Ring must be printed upside down, and can be printed with 0% infill. You may consider printing it with more horizontal layers to diffuse the light of the LEDs.
After printing the crystal ring, I had to use a file to clean up the parts where it connects to the
Support_Cage, otherwise they were a too tight fit. I had to use a 3 mm drill bit to clean up and slightly enlarge the holes on the
You may want to print the
Lower_Center with gold filament (or use acrylic paint as I did to paint it after printing).
