2021-06-04 - mastering OpenSCAD

i recently came across a mastering OpenSCAD book. it's free in online form or available for purchase in paperback. it made a great reading. even though i use OpenSCAD for well over half a decade now, i still managed to learn some new tricks. i wish i had this on my table back at the time i was starting my OpenSCAD adventure! happy reading! :)
