Helping Hands Addon for Adjustable PCB Holder Tool

I found that 3D printed helping hands were quite loose and prone to breaking, so I made an adapter plate that allows you to screw in your M14 helping hands onto a carriage for the PCB Holder Tool. It was made by simply threading two holes on the existing carriage plates in the original model. It will require two tightening rings from the original model in order to be fixed onto the rail.
