I made this instructable at Techshop Detroit.

The website for techshop is here:

Ok, On to the project!

The Collet wrench for our ShopBot broke. I set out to make a new one.

If you would like to make your own wrench with this file, feel free. It works great with our shopbot.  The file is below. (its in .DXF format.)

For this Instructable, I used:

.180" cold steel plate that I had laying around the shop.
A waterjet

Step 1: Design the file

I used some calipers to make measurements of our existing wrench.

I used CorelDraw to draw out the file, then I exported it as a DXF into the waterjet software.

I made sure everything was cool with the file and then I took it all to the waterjet.

Hey, that's great! <br /> <br />Care to donate it to the ShopBot kit? Last time I used the machine (July 3), we were still sharing one wrench between the Alpha and Buddy.
Yeah, As it turns out, Cold steel is not tough enough for this application. I'm going to try again with tool steel. I will update this Instructable as soon as that happens. The wrench worked for a few days, and then due to it being softer than necessary, it began to bind.
Gotcha. Shawn said that he would order some hardened steel on his next order, so he can make one for the shop.
