When readily available containers do not come in the desired form factor, 3D-printing can be quite useful. In this case, I wanted a tea bag holder that fit on a small ledge, allowed the tea bag labels to be read, … Continue reading
3D-Printed Hilbert Curve Absorbers
Fused filament fabrication (FFF) 3D printers are good for many things,1 but production of sharp points is not among those strengths. Thus, the traditional structure of millimeter wave absorbers—a periodic array of square pyramids—is poorly suited for production via FFF … Continue reading
