Legos, Tinkertoys, K'nex.... They are all fun and entertaining construction sets that can keep kids busy for hours. Now there is a new one out there, thanks to 3D printing. QalamSila are 3D printed connectors which connect to traditional hexagonal pencils to build objects in a similar way to Tinkertoys. Currently there are 3 kits available. The Buggy kit is the coolest, as it comes with shocks and pinions. Read more about QalamSila connectors at: http://3dprint.com/9937/qalamsila-3d-printed-sets
