I wanted something to organize the original cardboard pieces for NMBR 9. I scaled up the insert made by robertos and then made a few modifications to make the pieces fit and keep things from falling out. I then modified FedorSosnin's travel box to fit the entire thing. The lid doesn't fit very tight, so I keep a rubber band around it. It's a little hard to pull out the pieces when they are inside the box, so we pull the entire insert out for play. I love how compact it is for travel and nothing moves around.

When printing the box and lid print with a brim to minimize curling on the bottom.
