Ok I wanted to do this the first time I bought my welder but I just didn't have the time.So this weekend I got fed up of leaving my welding table just to grab some more filler rod that I went to home depot and bought all the parts and build my own container.It is very easy and you can add your own twist too it when doing your own,I will just give you the easy basic way of doing it on a $20 budget.

I made 5 individual containers but you can add as much as you want.Parts are:
Qty (6) PVC Pipe 1 in. x 2 ft.
Qty (5) PVC Tee Fitting 1 in.
Qty (4) PVC pipe clamps for 1 in. pipes
Qty (8) Dry wall screws 1 5/8 in.
Qty (1) 2 x 4 in. ply wood 2 ft. long

Cut (1) of the PVC Pipe 1 in. x 2 ft. into 3" in length to get a quantity of 4 pieces then insert them into the Tee fitting.Use a hammer and give them some light taps for the pipes to go all the way inside the Tee fittings.After you joined all the Tee fittings together,now place it on the 2x4 ply wood and put the clamps between each Tee fitting and screw them down securely in place using the dry wall screws.Insert the (5) PVC Pipe 1 in. x 2 ft into the Tee fitting and gently tap them in,you are now done and here is the final product.
