PCB text can now specify a colour. Added SOT23_6, TSOT23_8 and CAP1210 SMD packages. Added ESP-201 Wifi Module PCB. Added ESP12F Wifi module. Added tiny_buck converter PCB. Made 2p54joiner a bit longer. Fixed SOIC gullwing shape. Added Wifi antennas. Added Yunpen filtered IEC mains inlet. Added power jack socket. Added right angle option for LEDs. Added gear_motors. Added 686ZZ and 696ZZ ball bearings. Added two larger box section tubes. Added right angle option to square_buttons. Doesn't draw the frame yet. Added multiwatt11 package for L6203. Added ONS9143A 13A mains socket. Added radial electrolytic capacitors. Added LDE10_20B PSU module. Added screw_tearsink() to make horizontal countersunk holes. Can now have solid tracks on veroboard. Added veroboard_base() module to make an STL for a base with spacers. Corrected M6 spring washer thickness. Can now specify the height of a solder meniscus. slot() now has a center option. Added button_6mm_7 with a taller button. Added default fa, fs and fn constants used for drawing vitamins. These can be set via $default_fa and $default_fs that can also be set by environment variables: NOPSCADLIB_DEFAULT_FA and NOPSCADLIB_DEFAULT_FS.

//! Simple model of ball bearings with seals, the colour of which can be specified. If silver they are assumed to be metal and the
|
|
//! part number gets a ZZ suffix. Any other colour is assumed to be rubber and the suffix is -2RS.
|
|
//!
|
|
//! If a ball bearing has a child it is placed on its top surface, the same as nuts and washers, etc.
|
|
//!
|
|
//! Also single bearing balls are modelled as just a silver sphere and a BOM entry.
