Gundam RX-78-2 Perfect Grade beam saber
This is modelled to be exactly to scale from the one included in the kit.
When printing scale up 600% to have the size shown in the photo.
Everything is oriented the way I printed it with no issues. Printed at 0.16mm layer height, I've built in tolerances for where pieces meet so going up or down in layer height should not produce issues with fitting.
