Connector frame to allow you to make your own cubby house, play tent etc - any ideas?

Once I saw in a magazine from Playgroup a set of sticks and connectors you could use to build frames to then cover with sheets etc to make your own play tents, cubbies etc. The sort you build for a day and take down can be used inside and out - the sort of thing I do currently with clothes airers (coming to the limit of different structures can make with the airers) - but I have never been able to see anywhere again - I have tried google but seems am not putting in right words as just get more permanent cubby structures etc - does anyone know what I am talking about or seen them anywhere? (I tried the Chalk and Total Toys websites which I think were where the magazines came from to know avail)

I have seen those! If you google fort frame construction a few come up but I don't think they are in Australia - will keep hunting for you, I might have pinned on Pinterest! BBS!

ETA: Found it! Windmill toys have them - just type in fort in their search engine.

My kids had one when they were younger. I think I got it from either Kmart or Big W.

Thanks found it! Thanks to ~H~ for PM link too - Crazy fort seems to be key words I think I kept going wrong using word cubby.

Hooray! They are the ones at Windmill too!
