Please note: the print in the image was printed on a commercial Objet printer by 3D Print UK. And it is smaller than the original print of mine so you can print it on your printer.

[Update :: 27th August 2012] You can now create your own sign by using the blank sign body found in the derivatives section to the left. This will allow you to produce your own sign like the MakerFaire sign derivative made for MakerFaire. We would love to see what you come up with.

[Update :: 1st May 2012] As requested by MacGyver I have split the file up so it is easier to print. I have made some slight design changes too so you will not require any support. Now all you have to do is print the Base, Sign Body, Sign Legs and then glue together all the parts.

Thank you to MacGyver for pointing out the issues, If anyone has feedback or advice please do leave a comment below.

You will need to use support on the sign body but not on the base.

All you need to do is add a little glue to the slots and insert the legs on the main part and let to dry.
