I will be adding the following 2 parts to the store after I get done posting this.

The first part is a 3.58" double female with 7 slots cut into it.


The second part can be added to the slots on the first. Either via glue or better yet JB weld.


To create this. The grip section like this has a OD of 1.53" and is a comfortable grip as there are no sharp edges.



And then if you want you can add grips which fit perfectly between the spaces. The grip set we sell is the correct length by the way.
