DinoBank with reusable plug

I printed the plug with the octagon touching the build plate and with supports enabled (these are needed between the base and the tabs).

The DinoBank itself printed fine for me without any supports.

Printed with eSun transparent (yellow) PETG on an i3 MK3, everything fits together well and seems quite strong. Has taken a bit of a beating with my son carrying it around the house and inadvertently bashing it into things and is holding up well.

I removed the breakaway section on the underside, added a couple of slots so that the plug's tabs could fit through, and then created a plug/stopper that inserts and rotates into place.
