3D model description

We've all seen, and printed, the XYZ calibration cubes. Not only do they work great to test dimensional accuracy as well as z-wobble, ghosting and a host of other issues, but when printed in vase mode, they work great to purge filament in between color changes. However, I have found that some filament will print beautifully on the straight edges of the cube, but problems show up when printing rounded or curved surfaces.

To that end, I have made this simple, hollowed out, high resolution, 20mm sphere with a flattened bottom. The 0.8mm thick walls are meant to be printed with a 0.4mm nozzle. Printing at 40mm/sec takes just under an hour and uses about 4g of filament.

I am a self-proclaimed know-it-all. I will tackle any project regardless of my experience, or lack thereof. Always ready to learn something new. With over 25+ years experience in electronic repair and 10+ years experience in small engine / ATV / motorcycle repair, there is nothing I can't fix, modify or build.

Why a pepper? In case anyone is curious as to why there is a hot pepper embossed into most of my designs... My nickname is Pepper and that little pepper logo is a hell of a lot shorter than "Copyright © 2017 by Derek J.G. Tombrello" which is how I usually sign my work :)
