No-Support Marble

A quick and satisfying little 3D print that snaps together in minutes! This marble is designed with an internal core that locks two smooth halves together, making it a great easily printable marble.

Assembly Instructions:

• Simple Snap-Fit: To assemble, just insert the central core into one half, align the second half, and push them firmly together.

• Tip: If the friction fit is extra tight, a pair of pliers can help you squeeze the halves together more easily.

Print Settings & Tips:

• No Supports Needed: Designed to print cleanly right off the build plate without any messy support material or post-processing.

• Super Fast Print: A highly optimized model—expect a print time of around 10 minutes depending on your machine and speed settings!

• For the Smoothest Curve: To make the spherical curve look its absolute best and minimize visible layer lines at the top, use adaptive layer height or a finer fixed layer height (e.g., 0.12mm or lower).
