Printable 4x1

Printable shelves to go along with the holders. I haven't tested it yet as my printer is out of commission, but I plan on printing with PLA and PETG (Colors to match shoes) at a relatively low infill. The joint may be a tight fit, but I plan on sanding/filing it down to get the right fit. Measurements are in inches, so after joining the male and female parts it should equal the file name(eg. "12Female" + "12Male" = 12").
