Torus of Terror (Fractal Torus Shape)

EDIT 1/10/2017: Finally got around to printing the model! Check the instructions below for slicer settings and tips.EDIT 8/17/2015: Added "HighRes ToT Arch (Repaired) STL" for easy printing! I created this model to test my printer's capacity to handle overhang as well as calibrate its retraction settings. Printing instructions and slicer settings are listed below. I hope that you enjoy the model, and if you do please let me know! Print Settings Printer Brand: Ultimaker Printer: Ultimaker 2 Rafts: No Supports: No Resolution: 0.15 mm Infill: 20% Notes: Print two of HighRes_ToT_Arch_Repaired_STL.stl and glue them together to form the completed shape. Alternatively just keep the arch by itself. The make shown was printed on my Ultimaker 2 using PLA. I sliced the model in Cura (I had to scale the model down to 80%) with the following print settings: TIP: The very bottom of the model is quite small; strong bed adhesion is recommended. It may be easier to print if you "sink" the model into the buildplate by translating the model in the negative Z axis just a bit (so that the model has a larger footprint). Temperature: 200 C Build Plate Temp: 65 C Infill: 20% Print Speed: 50 mm/s Travel Speed: 125 mm/s Layer Height: 0.15 mm Build Plate Adhesion: Brim with 10 mm width Wall Thickness: 1.05 mm (3 lines) ZHop when retracted is enabledNO SUPPORTS! Post-Printing Post Processing Printing without supports may lead to some drooping. However after going over the entire structure with a good craft knife and cutting it all off, it looked perfectly fine. Also, I realized that the two halves didn't quite sit flush, so I sanded the ends of each a bit until it fit a bit better. I held the bottom half of the arch in a clamp and dabbed some Gorilla Glue over all the edges, pushing the two halves together, then letting the glue dry. That's it! How I Designed This About the Design This particular fractal is a slight tweak from CmdrChaos's "Low Calorie Torus" (http://cmdrchaos.deviantart.com/art/Low-Calorie-Torus-344056205). My version simply tweaks some of the totoricalIFS values (specifically mulA1 and subA1). This model was created using Mandelbulb 3D, a free fractal rendering software.
