Instructions

1. Copy all the scad files into a common directory.

2. The code has been tested using ABS, printed at .3mm layer height with 1 extra shell and 50% infill.

3. The parameters for the size of the bot, the board size, etc. are all contained in the file newsumo.scad.

4. It can be setup to generate a 3D view or printable views for the top, bottom, and sides. Just uncomment the line in newsumo.scad for what you want.

5. The caster used is from VXB bearings: vxb.com/page/bearings/PROD/Kit7766

6. The screws used to assemble it are #1 x 3/8 servo hold down from JR Hobby Hadrware: jrhobbyhardware.com/shop/index.php?main_page=product_info&cPath=108_109&products_id=255

7. This is a premlinary release. I am still working on adding a castering wheel. Also, a version sized for an Arduino board is in the works.
