oops, nevermind about that diff above, I found the boxotron-1.0, which includes the type option: http://www.thingiverse.com/thi...

I notice there's an unused "type" parameter that can be used to specify "tabs-only" (type=0) vs "tabs+bolts" (type=1). Below is the diff to have a global "type" parameter. Should be pretty easy to add a "bolts-only" type in there too.

I would love to try the script if it works on a PC. Sorry could not render the file. Could you please upload an uncompressed file or a zip file.
Thank you

Yes. I like such scripts too! Kudos! I know how much trouble it is to make it in Sketchup (first box took me 30 minutes). If you want a different size or material width you'll have to start all over and it takes another 20 minutes. When run without arguments it could ask for them (readline?). Everything is in mm, right? Oh and just a formal hint: You should add the GPL licence to the file too.

this is very cool! i'd love to see the ability to add t-slots like we use on the cupcake CNC. that way, you can easily bolt it together/take it apart.
