SummaryI was at a loss for desk space for my crystals/rocks so I thought I would design a nice little rack to fit [most of] them in. After printing I realized a few spots were somewhat small so I went back and enlarged those areas. This can also be used to organize or show off small items. Settings used are shown. The overall thickness of the walls are 2 mm. The average area for each slot is around one inch (some larger some smaller). print speed 50 mm/s perimeter extrusion width: 200% external perimeter extrusion width: 250% number of perimeters: 2Print SettingsPrinter Brand: RepRapPrinter: FlexMendelRafts: NoSupports: NoResolution: 250 micronsInfill: 50%
