Ok, now I think I'm starting to get a bit carried away...
After about 15 iterations I've finally come up with a slot/tab design that allows all these models to go together easily without glue or tape. They work well on both my paper cutter and on a laser cutter. I've tested it with 65lb and 80lb cardstock, and 100lb bristol board, and it works great. For inserting into inkscape documents. Note - the sizes are very specific - if they are resized, the various clearances for the slots have to be adjusted. Here is the file with 1", 2", and 3" tabs and slots: tabs.svg.
I updated the truncated icosahedron (soccer ball) model with the new tabs. My first version of this model (see a couple of posts back) took almost 2 hours to put together with glue and tape. This one took about 15 minutes, and half of that was pre-creasing all the folds.
