This is a simple holder for a folding meter for Kupper (Küpper) pegboards.
Unfortunately, folding metres are not all the same size. They are for example 2 metres long, but the width and thickness of the individual links are different.
I need an opening of 32x17mm and 45x17mm for my folding metres. If one of these sizes suits you, you can select one of the two print plates in the print profile.
Otherwise I have attached the f3d file. It has two user parameters for length and width. These are the sizes of the opening.
I hope it is useful for someone.
