Wug Tree Ornament

prusaprinters

This is a wug tree ornament. A wug is a little mascot of the linguistics field based on Berko's morpheme study. I've used Gawne & McCulloch's CC0 wug image reproduction, scaled and converted to 3D in OpenSCAD. Default size when assembled: 44 × 54 × 4 mm. 5 g filament / 12¢ filament cost / 26 minute print time.

Post-Printing Remove the two halves from the print bed. They may be quite fragile. Apply a thin layer of glue to one side, making sure the legs and ring have some glue coverage. Align and press the two halves together back to back. Remove excess glue before it dries. White glue / PVA works quite well for opaque PLA. Clear glue might be better for translucent prints. How I Designed This I extracted the inner contour from Gawne & McCulloch's SVG figure in Inkscape. The centre of mass was calculated using Inkscape's Visualise Path → Measure Path extension. This is used to place the hanger ring to make sure the wug doesn't hang squint. OpenSCAD (≥ 2019.05) was used to emboss the inner contour half the height of the outer contour. As the source image is CC0, I published this under the least restrictive licence that Thingiverse allows. Category: Creatures
