customisable ice cube mold

thingiverse

# Easily create personalised ice cubes # * No CAD skills required * Simple print. No supports. * Also useful as molds for kinetic sand or play-doh Included examples (.stl): * ICE * GIN * RUM *IMPORTANT:* Ice molds require flexible filament * The safety of 3d printed materials for food preparation is highly debated * I personally use filament that is certified as food-safe (Eolas Prints TPU, Spain) * I also use a non-toxic hardened steel nozzle, rather than a standard brass nozzle ## If you've never printed with flexible filaments before: * it's definitely worth a try! * start with a semi-flexible filament (e.g. 95A TPU) * start with *this* design (Seriously. It's dead easy.) To release the ice, run hot water on the back of the mold, and then extract with a blunt knife. The more flexible the filament, the easier the extraction. ## How to customise: * Install the free software [OpenSCAD](https://openscad.org/) * Do a 30 min online tutorial to learn the basics (use the editor, preview, render, and save as .stl) * Download the [sledge typeface](https://allbestfonts.com/sledge-typeface/) * Install the typeface so it's accessible to OpenSCAD (see [forum](https://www.reddit.com/r/3Dprinting/comments/ee8011/anyone_know_how_to_add_a_font_to_openscad/)) * Move gin_ice_mold_demo.scad and icemold.scad to the same directory and open gin_ice_mold_demo.scad in OpenSCAD. * Modify the text. Modify `mold_length_x` to change the length of the ice cube. * preview (F5), render (F6), and save as .stl Note: if you don't want any wall text, just change the variables to empty strings (e.g. `wall_text_lhs_top = "";`). ### Further info: Many thanks to the support of my work colleagues at Munich-based [TNG Technology Consulting GmbH](https://www.tngtech.com/en/index.html). The initial concept came from a hobby project during a TNG Techday (similar to Google's "20% time"). The design is also on [GitHub](https://github.com/teese/icemold). The OpenSCAD code is released under a permissive licence that allows commercial use.
