A modular tiny whoop gate that is very compact so it will fit in most backpacks. You can make any type of gates because of its modularity.

An 8mm diameter stick,straw,metal/plastic tube is required to assemble a gate (the lenght is variable). To make the feet of the gate you should use 1 stick or any other materials i mentioned  and the tri non block  .The tube connector is just to connect 2 straight sticks and to make the gate bigger.
