Negative Boolean Body for Sy's Peglock

I have become a tad bit obsessed with this peglock system, and made myself a solid body to boolean subtract from any model in order to use the universal board attachment.

Add this STEP file body into any model, use a subtract/remove operation to create  a cavity in your part, and then BAM mount it to a pegboard with Sy's universal attachment. 

STL file also included in case you're a masochist. 

I took Sy's part template and simply created a solid of the negative space.
