// Features:
// * roundedbox(dim, r): Rounded boxes
// * pcbbox(dim, r, innerr, w, top, ridge): Rounded PCB enclosure, with bottom and top part (height given by top)
// * pcbmount(type, pos, dia, len, innerdia, holedia, pcbthick, screwdia): PCB mount (type="screw"/"clip"/
// * pcbscrew(pos, dia, innerdia, len): Screw mount inside the box to screw a PCB to the enclosure
// * pcbstackon(pos, dia, len, holedia, pcbthick): Stack-on mount inside the screw to hold a PCB
// * boxscrew(pos, dia, innerdia, screwdia, len): Screw holder to screw the top and bottom parts of the enclosure together
// * boxcutout(...): Cut out parts of the box
