Fully printable 15mL Lab Rack (stackable)

Thank you for considering my handy stackable lab rack for 15 mL falcons!My motivation for creating this model was to have a fully printable lab rack for 15 mL falcons that is rigid and can be neatly stacked and stored in our -80°C freezer. The top part has indentations where the feet of another rack will slide into and therefore provide secure stacking. The dimensions were chosen to fill the X/P-series’ print bed to make it 2 print plates instead of 3 and therefore shave off a bit of print time. This resulted in a 5x9 rack. (It is possible to extend the dimensions to a 5x10 rack on 3 plates. If you're interested, drop me a message!) The actual dimensions can be viewed in the technical drawing: One rack consists of 3 parts. Assembly is recommended in the following order:middle part into bottom parttop part into middle/bottom part comboTolerance between pins and corresponding holes is 0.1 mm which for my SUNLU PLA+ printed on a P1S results in a firm press fit that won’t break the pin
