Hi-Hi flat pack

This thing is a variation of my Hi-Hi-Hi v3. ( https://www.thingiverse.com/thing:6854589 ) Now you can build it yourself! And it is very fun to do so.

Instructions
1) remove all the parts from the tray
2) slide two of the long "U" shaped pieces into each other to make a + shape from a birds eye view
3) repeat step two until there are no more long "U" shaped pieces
4) slide a short "u" shaped piece into the long gap of A "H" piece
5) repeat step four until no more pieces are left
6) insert all the + shapes into the base board
7) insert all the rest of the pieces in the correct places
