I designed this drying rack to be scalable to fit multiple items like test tubes, beakers, Erlenmeyer Flask, graduated cylinders, etc. I used a minimalist design to save filament and for fast printing. At 100% this will fit inside an 11mm opening and be 2mm thick. It will also be 50mm high and 50mm wide. Some sanding may be needed to fit properly depending on your printer and setting. The ones in the picture were all printed at the same time on a 200mmx200mm bed with 15% infill and took about 3 hrs on my older XYZ DaVinci 1.0 printer. The smallest is 100%, the middle size is 150%, and the largest is 200%. Both parts of same scale are needed to make 1 stand.
