Kids Lego set was missing a piece, so I made this to fit. Printed using a 0.2mm layer height with a brim (to prevent any warping). Printed better for me when multiple instances were done at the same time. Fits very nicely, but the PLA I used is a flat orange, whereas the original Lego pieces are shiny. PETG would be a good option to blend a bit better.
