Custom attachments for a multi-cutter – Steel, 4 parts

Description:Aide

These parts need to be machined in a resilient steel such as A2 tool steel. They are a custom attachment for a multi-cutter (sold by Fein Bosch etc) that extends the reach of a multi-cutter.

There are 3 part designs here but I need 4 parts machined because I need two of the “counter plate” design (the one with 3 holes). Each counter plate works in a pair with the other two parts. I've included designs I made in FreeCAD software (as a zip) and design images. Some of the design details are not vital, I have written the absolutely vital stuff below...

The shafts on the binding end and cutting end parts must have a 6mm diameter and must enter the holes in the counter plate and fit tightly. I think H9 holes and e9 shafts would work well.
The shafts in binding and cutting end plates must be 44mm apart (from the center of one to the center of the other)
The counter plate and the main surface of the other two parts must have a thickness of 3mm and the shafts must be 9mm long.
The binding end part must fit tightly onto a multicutter and the cutting end part must be able to have a multicutter blade be attached to it. The images show this working with only 4 of the 12 indents that a standard multicutter would use to try avoid the parts being impossibly complicated to machine.
All parts must have rounded edges.

Please contact me with any questions or your thoughts on the design.

Thanks
