Ambigram Letter Blocks for Kids

thingiverse

Ambigram Letter Blocks for Kids Each block contains 2 letters, each visible from a different angle. You can combine blocks to spell out the whole first and last names of a child so they can learn to spell both names. I've made these for several kids and they go over well. Some letters work better than others. Some names work better than others too -- if the first and last names are very different lengths, this may not even make sense as a project since many of the letters will be empty. The included stl_files.zip contains every possible letter combination as a 50x50x50mm block, so you don't need a CAD program at all if you don't need to make modifications. Technically A/B and B/A are different shapes because the letters have different relative orientations, but I only included one chosen arbitrarily in the included file. For more tuning, open it in OpenSCAD. All of these need a lot of supports, and you'll have to cut them out with a utility knife. You may want to lightly sand to get rid of the remaining markings from the support (I didn't do that above!). I recommend high infill for these if you're going to let a kid play with them. If they're just for display, no infill is needed. SOURCE CODE: https://github.com/dfeldman/functional_forms/tree/master/ambigram_blocks
