Number and alphabet blocks

thingiverse

You're free to select 6 characters or create your own blocks from scratch. Test prints can be a great way to experiment, and you might even consider gifting them to toddlers to play with later. Just keep in mind that the current scale is almost 1 inch, so it's best to scale up when slicing if you plan on giving them to little ones. Choking hazards are a serious concern. To avoid any issues, be sure not to print with supports. Removing them can be a real challenge, and the next layer may not stick out more than 0.2mm even after scaling. I've tweaked the OpenSCAD file to double the resolution for the slopes in the letters, but unfortunately, I haven't re-rendered or exported the STL files yet. If you'd like additional quality control, just let me know by leaving a comment below.
