Multi Print spool holder

I had some filament that did not fit on the standard spool holder of my ender 3 so I designed a stand to go on the desk next to my printer to hold multiple spools. This is what I came up with. The rod hole is 10mm by default. Will need 2 uprights, 2 female base and 1 male base to make it 19.5 inches long. You can print multiple bases to make it larger if you want.
