@gaius619 Thanks so much for the input... So having this totally CNC made makes it a great platform for people to hack on. The idea is to encourage people to design. We made them a stable and sturdy bench, now they can make it their own anywhere there are CNC tools, which is a lot of maker spaces and schools all over the country.
Now I did design the top to be able to be fabricated on a table saw should you want a replacement, or to make your own and customize it. I could see someone cutting out the top and putting holes and slots in it with regular tools for different tools and things.
If you did want to make these yourself and didn't want to pay a lot of money to get it done you could always have patterns cut out by someone with a CNC. Then you could use a hand router to make copies. You could take your originals and modify them too with regular shop tools if you wanted to change things like the height, width, etc.
If you were patient enough you may be able to print out the plans full scale at a local print shop for just a few dollars and use a regular band saw to make the shapes too...
