I wanted to print the base with different color letters, so I split the letters using 3D Builder, and added pins for lining up. Letters should press fit into the base.

Printed using Entina Tina2, Creality Matte Black and FlashForge (I think) Silver. Base was printed at 0.2mm and the letters 0.12mm. Had to scale the models down to 65% due to my print bed size, but they were edited at full size.
