Description
Simply place the model in the centre of the bed and scale it to suit. Do not add bed adhesion features like brims or mouse ears. The model is intended to lift from the bed in the corners if shrinkage occurs.
This model will take some time to print, but shouldn't use too much filament (~70g).
This model is used in the following video:
This simple shape was designed to promote warping. This means a bulky centre section to retain heat, and skinnier legs pointing out from the centre that will cool much faster and shrink. The part gets thicker as it gets taller to exacerbate this. The contact patch with the bed is much smaller at the extremities, further promoting the legs to peel up from warping.
The central hole is present so the completed piece can be used as a the base of a stand using a 10mm bolt through the middle.
An overview of why some shapes warp and others do not can be found in this video:
