Ice Cube Tray

The inspiration for this design came out wanting to find a way to connect 123D Design's Rectangular Pattern tool to a real world design that my students might need. Full lesson detailing how to scaffold this design into a series of lessons will come soon! In the meantime, feel free to print - wall thickness of this particular design has been optimized for 0.4mm extruder nozzles (the default size for Makerbot printers).

Update (3/21): Rev 1 is too thick for PLA (may be okay for other materials?) and so is not flexible enough to twist out ice cubes! Test rev 2 soon - I'd suggest not printing the current model. Please check back!

Update (3/23): Rev 4 - freshly uploaded - prints on the Makerbot Replicator 2 reliably and comes off the build platform flexible. Just need to give it the freezer test to see if the cubes break away. From here, I think it's going to be a matter of tweaking advanced settings (supports) and/or working with print orientation or finishing techniques. O
