A Catch-All Tray with Goats (OpenSCAD)

Introduction

The model “Catch-All Tray.stl” is created with a OpenSCAD script and it is based on two other designs:

1. The Smug goat by VoxInaudita. License: Public Domain.
2. The Irregular Grid Flexible Sheet by Steve DeGroof. License: Public Domain.

The OpenSCAD script is also included and is Public Domain and the resulting stl file is also Public Domain.

Slicing and Printing the stl file

Supports are required.

The Flow for the support was set to 95% and the Density to 10%. That makes it easier to remove the support.
To remove the support in the middle, I used a screwdriver with a hammer to cut into the support all around. Then I removed it with long pliers and cleaned it with a knife.

The Z Seam is set in the center, so each goat has the Z Seam at the backside. The Cura slicer can set the Z Seam in the middle by setting X and Y to zero and making it "Relative".

The SilkPLA that I used is brittle and that helped to remove the support. The disadvantage of SilkPLA is that the Z Seam is visible on the inside of the bowl.

Other slicer settings are: 2 Walls (2 perimeters), 4 Top Layers, 3 Bottom Layers. Grid Infill 15%, Layer Height 0.2.
With a Size of 100%, the resulting weight is 130 gram.
A layer height of 0.16 would be better, but that would increase the printing time from 12 hours to 14 hours on my printer. 

Using this script with OpenSCAD

OpenSCAD is free software: https://openscad.org/

To use the script, download the Smug Goat and put the stl file in the same folder as the script. Open the script in OpenSCAD.

The Smug Goat is a large stl file. The OpenSCAD version of 2021 is too slow to render it. I used the (development) version of 2023 and I turned on some optimizations.

You can use any animal that you like, but OpenSCAD can not render every stl file. I have added a rendered picture of a bowl with lions. Instructions how to make it are in the script.
