Please visit http://OpenSCAD.DIY3DTech.com for more information on this and many other projects! As in this episode we will be looking at programing the Ultimate Widget as I was surfing the YouTube InterWeb and found Keith’s Test Garage (https://www.youtube.com/channel/UCiANfkB8tb8V3QnN9zvES6g ) and a video he created caught me eye and I got thinking, I can design this in OPEN-SCAD and also why does it need to be limited to only router bits! So lacking a name, the ultimate widget was born!
