Springo Sphere

In a world first, it's a big ball of springy springo wonder! This weighty print takes some post-processing finesse, but the result is something special.

Download includes the Springo Sphere Half, and an optional support model to reduce the amount of support material _(Use the Support STL with supports disabled,_ or _don't use the STL and enable standard supports, but make sure they aren't generated between the layers of the springo)_

I got the best results printing with 3 outlines/shells, 0.15mm layer height, and enough solid top & bottom layers to make the spring part solid infill. If using the support part, I suggest giving it separate settings, since it is sacrificial. You can get away with something very minimal like 12% infill, 0 shells, 0 top or bottom layers.

After carefully separating the coil with a thin palette knife, I trimmed off the bottom of the coil on each hemisphere and welded the parts together using a 3D pen (https://makeanything.design/favorites/#3Dpens) (I used ABS settings even though I printed in PLA to make a stronger connection). I used binder clips to hold the two halves together while doing the 3D pen work.

You can see my video segment about printing and assembling the sphere here (https://youtu.be/DQ1PZZgt28w?t=224).

Pictured model was printed with Aqua Glow-in-the-Dark PLA filament similar to this one by Polymaker (https://amzn.to/3OyFRiI).
