This is a remix of the question block planter from Super Mario Bros.

The edges now have pressure fit dovetail connectors an the bottom snaps into place once assembled. There is absolutely zero glue required for assembly.

Unfortunately, this means one edge of the side pieces require a small amount of support; however, I think this is a more than reasonable trade-off for not having to glue and tape and clamp and wait and post-process. I hate glue.

I also slightly resized the question mark dot to hold in place by itself as well.

The question mark can be a little snug to line up all the edges but with enough pressure will pop right into place.

The model is successfully scalable down to 50% size and still assembles great.

If you print it smaller and it works, post a picture an let us know!
