Structural Engineering Saturday

When we were overjoyed with our Cube which we were given for Christmas, Äiti went online to see what similar things were available and a huge box of goodies arrived earlier in the week. Inside was this. 

Sampo was a bit unnerved by all  the tubing and joints, In the meantime Äiti was thinking how great it would be to have a 3-D printer and to construct this sort of thing.

She assembled it in minutes, and Seppo was first to sniff it out.

Then more mancats came to inspect it.

I took  a cursory glance as I dashed past.

 And Stran wondered about falling asleep under it.

Later a load of kissanminttu was rubbed on it and surprisingly it stayed upright. We were impressed.
Now what else was in that parcel ....?
