Spooky bowls

thingiverse

Two spooky Halloween bowls for serving treats (or tricks) come in two quick prints that require no supports when printed flat. The trick to getting them bowl shaped is to heat them up in an oven over a heat proof container, then shape when hot. Once cooled the bowl will be set in its 3D shape. This process requires use of an oven and hot items so please use appropriate safety gear (oven gloves) and avoid touching anything with bare skin. Print Settings: Printer Brand: Ultimaker Printer: Ultimaker 2 Rafts: No Supports: No Resolution: 0.2 Infill: 100% To convert the flat print into a 3D bowl, use this process: Find an oven/heat proof bowl to act as the mould for your print - metal or Pyrex works well. Place the bowl upside down on a baking tray and add a baking silicone sheet underneath to prevent it from slipping. Put the bowl and tray in the oven with the 3D print centered on top (though off center will give you a different effect). Turn on the oven and set temperature to the lowest print temp for your filament. Watch the 3D print as it heats, it will start to go floppy and drape over the mould. Once up to temperature carefully remove the tray from the oven and place it on a heat-proof surface - use safety gear! Before the plastic cools use oven gloves to flatten the plastic against the sides of the bowl. You should be able to make this fairly flat, if not you may need to heat the plastic a bit longer. Once happy with the shape of the bowl let it cool completely. Remove from mould and your 3D print is ready to use!
