Kitchen Shelf Paper Towel Holder

Simple two piece paper towel holder that I designed to fit on the lower shelf of my kitchen cupboard, 16.4mm thick. 

I needed to keep the clip fairly thin (3 mm) so my cupboard doors would still be able to close, so I added a modifier in the slicer to print the right angles of the clip with a higher infill density for added strength.

Adjust the STEP file as needed to customize it for any shelf.
