Stackable paper holder desk landscape

Rework of paper holder to be able to stack them (as promised).  Beveled bottom and top with triangles (added & removed) to prevent sliding left-right, front-back.  I printed mine w/o top & bottom layers to save 1&½ hours of print time and the waist of all that filament.  Still strong as a mule but maybe don't put in a full ream of paper above the bottom layer?!?

Stackable now with these mods.  Not compatible with origan model due to mods.
