Nested ABHA Rodin Coil Frames - 1st & 3rd Order

thingiverse

This is the followup of my ABHA Rodin Coil Frame (Phi proportions, 36x36 pattern) design, which can be found at => https://www.thingiverse.com/thing:2710529. The grooves on the former follow the angle of the wiring. This design consists of 2 ABHA Rodin coils nested, according to Tom Barnett's research. This has a 400mm outside diameter 3rd order Rodin coil, with 36x36 pattern, which inside it has a 247mm outside diameter Rodin Coil with a 36x9 pattern, Phi proportioned. How to route the wire on the 400mm 3rd order coil refer to the above design link. You can find the maths and example calculations in the PDF that is at the files section of this project.The main research into this design configuration can be seen here on Tom Barnett's video link, starting from the actual section that is relevant, https://youtu.be/kxuU8jYkA1k?t=304. Wire routing on the large one is identical to the 3rd order design with the link above. Of course, you need to build the 1st order, smaller coil first. The wire routing is exactly the same as on the big one, every second groove on the adjacent former/rib, see the colour marked former ending on the relevant photo. On the small 1st order coil the wire routing passes through the centre of the coil 4 times while it goes around it once. On the 3rd order coil, large one, only goes around once in one pass, pattern 36x9. On the large outside 3rd order coil passes through the centre once and goes around once, see images. Once the inside coil building is completed place in the centre of the large one and use the clips to hold them in place. 3-4 clips will be sufficient to hold the assemble together. See close up image of the clip and how to put it on, last image of the assembly. As you route the wires around it, it will be even more securely locked into position. All the printer settings and notes regarding printing is identical to the project that has the link above. If you decide to build this configuration in a smaller scale, I would suggest not to reduce it below 75% of this designs original size. All parts will fit a 200mm x 200mm print bed. Update: I provided for the 1st order coil two different version rings for the former. V1 is with 18 former and the V2 is for 17 former. V1 allows the coil to wind around the torus continuously, images with the yellow winding on the green semi transparent frame. V2 allows the winding of 9 separate individual coils on the torus which can be experimented with series or parallel coil connections and even vary the coil polarity.This winding is shown on the images with the transparent blue frame 1st order coil and has two different winding colours. I also included the 9:9, the basic building block, and the 36:36 pattern which will allow you to build and experiment with different map configurations and sizes while modelling the different order coil vortexes.
