This is a home made drying case, but very well built. Measurements are 37Hx 19.5x 17 The framing is made mostly of 2X2s I am using a very heavy almost clear plastic sheeting to cover it, it comes with extra also you if you want. The bottom is 1/4 plywood with a 4.5" Square hole that has a plastic case you can fit pantie hose into as a filter & can easy be replaced with a clean pantie hose, this is where air will be drawn through, i have extra pantie hose if you want also. On top is removable heavy wall paneling with a 4.75" fan to draw air from the bottom through the cabinet. I made this so as to sit out side on the porch with some sun, as thats important because it adds a lot of beautiful coloring depth to the violin, also you can't dry a violin with oil varnish inside, its to toxic. This really works great for oil varnishing just about any small instrument. I've used this only once for one violin.
