Dodecagon Vase

thingiverse

There it is: My first vase design! It's built from a dodecagon. In geometry, a dodecagon or twelve-gon is any twelve-sided polygon. I've built it using Autodesk Fusion 360. Originally, its Z-size is 150 mm. But it shouldn't be a problem to scale it on the Z-axis to whatever you want (or your printer can do). I've made a prototype with 100 mm, printed the vase at its original size and scaled the Z-axis to 180 mm in PrusaSlicer (just check out the images). All tests have been done on a Prusa i3 MK3S. On Prusa printers, you can easily use a layer height of 0.25 with quality filament like Prusament to speed up the print (assuming you're using a 0.4 mm nozzle). It shouldn't have a top layer but if so, don't forget to remove it in your slicer. From my point of view, the best practice for a vase is: - Load the file into Slic3r - Navigate to "Print Settings" - Enable "Spiral Vase" mode - Set perimeters to whatever you want and answer the slicer's question with "No" - Vase mode is disabled (should be okay) - Go on to specify your settings Printer settings on Prusa i3 MK3S (slicing done with PrusaSlicer 2.1): - Layer height: 0.2 mm (also first layer) - Vertical shells: 2 - Horizontal shells: bottom = 6 | top = 0 - Seam position: Random - Infill: 0% (this is one of the settings taken over from enabling the spiral vase mode at first - see above) - Support material, rafts, brim: none - Speed: original slicer settings = unchanged - Filament settings: first layer = 205° | second layer = 200° (always try lower temperatures as recommended or build a temp-tower of the filament first) - Watertight: NO (use liquid rubber spray like "Plasti Dip" to make it watertight after the print) Filament used (check out the pictures): - Prusament "Galaxy Black" - Eryone "Transparent" - OWL Filaments "Petrol" (prototype) Issue: if an error occurs while slicing, the top 3 layers are partially empty! I think this won't affect the print. But at this point, I don't know why it happens (I hope to fix that in the next version). Only tested on Prusa Printers/Slicer!!
