Nice Little Shelf 3D print model

I wanted a small shelf to keep small stuff off my desk, but handy, especially the always-changing bits of materials samples for projects. So I made this one. It measures 8-1/4L x 3W with a 9/32shelf thickness. The front lip angled up at 15° and is 1/4 wide. The mounting tabs are 1H; the large bore is 3/8D, and the notch slot is 3/16" wide. Printed in PLA with 0.3 layers. No supports, no post processing. (Note that the lower shelf has no lip - had some air printing there - but it was done enough to be usable...) Nice little shelf. Should be scalable.
