This is an extender for the common quick-action type clamps. It might not fit every type.

This is for those instances where your clamps are just too darn short for the job. 

You will need two sets of M6 screws and nuts to insert into the fasteners. There is a top to glue onto the fasteners, but it is optional.

You remove the ends of two clamps and place them inside the extender. You then secure them with the fasteners.

You will want to print the extender to be as durable as possible, as it will be subject to a lot of clamping forces. Use a strong filament and print the model laying down (like in the model preview) so that the layers are not structural weak points.
