Doing a little work from home after Ian and needed something to prop up the paperwork I was converting into CAD files for water jetting. Whipped this up in a couple minutes and printed it while I was working. Print in separate pieces flat on the bed with 4 perimeters, no top or bottom layers and 10% hexagon infill. Parts slide together and come apart easily for transport. Can be glued together if desired.
