Organization Cool Things to 3D Print Shoe Support
Keeping your kicks high and dry from the catastrophe of closet clutter, the Shoe Support is a simple solution to a simple problem. Wedge your shoe into the opening and let gravity do the rest.

3D Printing Cool Things to 3D Print Reittec Polisher
This Reittec Polisher uses household items, easily sourceable electronics and a whole heap of silicon carbide sand to take the effort out of post-print processing. Once printed and assembled, all you need to do is throw your print in need of processing into the sand for a long tumble. Several subsequent tumbles in increasingly finer grades of sand later, and you have super smooth parts with not a lick of sandpaper or cans of elbow grease in sight.
The model’s maker outlines the basic assembly steps on the Thingiverse page, but expect to have to fill in a couple of the blanks. Overall though it looks simple enough. For a better look at the build check reittec’s Instagram page.

Storage Cool Things to 3D Print Parametric "Print in Place" Containers
We’re a lazy bunch here, which makes anything that’s print-in-place – giving complex function with the minimum of effort, no tinkering required – pretty special to us. And these single-print self-fastening boxes are pretty special. We could hardly contain our excitement for these containers if you will.
There’s even a Fusion360 file on the link, letting you scale the model as desired without ruining the hinge’s printability (scaling directly in Cura will mess with the clearance, loosening or tightening the hinge beyond usability.)

Eventually, once your goal has been reached, the My.Mo closes, locking the money down and indicating to you that it’s time to spend. Make a wish and get saving.
