Devo Energy Dome Hat - Remix No Supports

thingiverse

For a printer measuring at least 260mm by 260mm, this design is designed as a single piece. One of my initial prints came out well when done in full size and with supports placed top-down. However, it used nearly half a spool of filament and took two whole days to complete. My second attempt, also for a friend, involved trying multiple orientations and support structures, but all continued to estimate an excessively long print time while using a lot of material. In order to eliminate the need for supports, I came up with a new approach by placing cones inside the hat and then subtracting other cones from those to create small conical support ramps (using Tinkercad). This process took about 15 minutes. This revised design uses 60% less material than my best estimate using the original model with supports. Additionally, its print time has been reduced to 13 hours instead of the initial 42 hours required for all the support and retractions needed.
