This is not a complex model.  This is a short homage to living in a world where you can design, print, and use objects faster than going out shopping.  This piece, which is very simple, represents what it means to live with a #D Prusa printer and a stock of filament.

While moving furniture, we have a set of shelves (1x3 foot base, 2 feet tall) we wanted to put over a heating vent.  We needed a way to raise them up about an inch (25mm) to allow air to flow and to be even on the floor.

Went into Tinkercad (tinkercad.com) and created a simple cross to lift up some shelves, assuming that I'd use two for stability.

Printed with 4 walls and 50% infill with PETG.  Stable enough for shelves measuring .  Nothing special in this model, just created two extruded rectangles, printed, and put into place after 10 hours of printing.

Faster to design, print, and solve my issue than ordering online and allowed me to focus on other things at home while the pieces printed.
