I created these custom tile elements using clear acrylic on a Glowforge laser printer and shaped them to snap into place on the outer structure. Spaceship Earth triangle tiles are unique and need to reflect the light a certain way. One side of the model is as it looks from the outside of the geodesic sphere and the other side shows the rotating scenes inside.

Whaaaaaaaat! I didn’t even know an outer cut with an inner score? engrave? could fold to make such a shape!!! Living and learning from the best in this forum!!!
I needed very thin acrylic for this so I ordered 1/16" thick 12" square sheets from Amazon. When I snapped the two score marks I applied acrylic cement with a precision tip bottle into the three grooves. In about 5 seconds it set up enough to hold itself. I used a candle to heat up the prongs enough to bend them down and a lip for them to snap into place. This acrylic has a film mask on both sides…after it was shaped I removed the bottom film to spray paint and then removed the top film after painting.
I think the bottom film helped keep everything together and lined up after snapping the score marks and during cementing.
