This is a very useful model - at least to me!
It's a writing pad holder meant to hold a standard 5"x8" writing pad on a refrigerator. It can be used for various notes, lists, or whatever! These notebooks are very affordable and can often be found in multi packs for just a few dollars. The pen folder is large enough to hold a sharpie sized pen so, most pens and pencils should fit without an issue.
Assembly is simply done by using super-glue to join the parts. There are slots on the sides to accommodate the pad holders. The back side has my logo so make sure to glue the pad holders in the right direction - so that the pad is held on the FRONT side. The back also has indents to accommodate foam tape for sticking onto a clean flat surface.
I would like to change the base so that the back side is more of a honey-comb. I designed it in openSCAD and I'm not sure how to do that yet. Current design takes a few hours to print the base and uses more filament than it really needs to. Although, its not that bad since it's only 2mm thick.
