One 8th of a Lego compatible carousel for a 4-Mation 3D zoetrope.

Print 8 segments for a whole disc. You'll also want to cut 16 100mm lengths of square rod, 8mm thick or less. This is used to reinforce and crossbrace the segments from underneath. The crossbracing makes the segments into one flat carousel.

There's an STL file for a single segment, and a pre-supported Lychee file for printing 2 segments on a medium sized resin printer like the Elegoo Saturn or the Anycubic Mono X.

Latest version uploaded Oct 21 has slight adjustments to stud size for better universal fit to both genuine Lego and knockoff-Lego from Aliexpress. Previous studs were also slightly too tall.

Note - exposure settings in CTB file are for Siraya Tech Fast mixed with other lower cost resin, so if you're using pure Siraya Tech resin, you could lower the timings, if you're using a cheaper slower resin you'll need to up them.
