Spiral Fidget! - Easy to Print

This fidget is great! However, I have had consistent issues with the nut getting fused to the endcap. Adding supports in between the endcap and the nut was ineffective because the space was too small, and the whole thing would meld together. So, here are my solutions:

1 - I raised the nut about a third of the way up the bolt. This will allow for organic supports that can be easily broken off. In PrusaSlicer, use paint on supports and smart paint, and select the underside of the nut. (You can set the “XY separation between an object and its support” to 75% to make it even easier to break off the supports.) 

2 - I separated the nut and the bolt. You can pause the print at 71mm and insert the bolt. (For convenience, I also split the nut and bolt into separate files if you want to print them is different colors)


Printing Guide:

Infill - 100% - I like printing this at 100 percent infill. This gives the fidget a heft that is far more gratifying than a lighter infill. 

Layer height - .15mm - Although the nut will slide even at a .3mm layer height, I would recommend using .2 or .15mm heights. This will allow for a much smoother gliding motion of the nut down the bolt. (Using smaller layer heights slows down the print; however, in PrusaSlicer, you can change the “Combine infill every” setting to 3. This will allow the infill to be printed at .3mm while the external portion of the model stays at .15mm)

1 - Raised the but. 2 - Seperated the nut and bolt.
