Token based on the Pass the SALT 2018 conference logo.
I'm sharing it mostly for its design process, hoping it can inspire other people.
The STL is duplicated 63 times (to get 64 tokens) and auto-arranged in a 8x8 grid.
To print it in two colors:
- Setup your slicer to stop the print at 1 mm height
- Turn heatbed on again for faster resume
- Turn extruder heater on again, keep Z steppers turned on, change filament
- Remove first filament track from the heatbed for priming nozzle
- Setup your slicer to start the print at 1 mm height
- DON'T setup any additions (skirt, raft,...)
- Disable homing (G28), at least don't perform automatic Z homing
- Make sure the slicer goes to proper X & Y positions before lowering Z, to avoid colliding the first layers when priming the nozzle
- After priming, make sure the slicer raises Z before moving X & Y.
The logo was initially made as a thick stroke in a SVG.
Using Inkscape, we first convert stroke (and text if any) into path, then get union of paths to simplify the design into a single path.
For openscad conversion, there is a nice Inkscape extension paths2openscad (as
.deb or put
.inx files in
Then, just use
extensions / generate from path / paths to openscad and you get a nice SCAD file.
