This model is based on the Reinhardt figurine from Incredibuilds and don't require glue to be assembled. I recreated it because it is not sold in my country and i made some modification.

The pieces were modeled with a thickness of 1cm. Pieces that fit together have a gap of 1 mm on each side and the pieces that slip between them have no gap.

The model in the photo was printed with a size of 35% on an ender 3 and a cr10s pro (because all the parts do not fit on the ender 3).

The folder contains STL files at 30% original size (which can be print on the ender 3) and each separate part at 100% size.
