FREE Neo7CNC Design Files – Vol 1

By April 12, 2020July 6th, 20213D Printing, CNC, DIY, How-To, Non-CNC, Uncategorized

Here’s the first installment of Free Neo7CNC Design Files.  I created these files over the years and I’d like to give them away.  Many of them can be 3d printed and there are several that can be machined, either manual or CNC.  The most notable files in this group are the design files for the bracket system I developed that helped me create the KR33 CNC machines.  These CNC machines use the, very easy to work with, aluminum extrusion from 80/20.  Series 10 in the 2 x 2 inch size to be specific. The bracket system allows to to combine THK KR33 linear actuators and the aluminum extrusion into a compact but very capable CNC machine, pick and place machine or whatever contraption you come up with.  I’ve always purchased my 80/20 aluminum extrusion from their store on eBay named 8020inc but they have closed that store.  You can now buy direct from them online or via Amazon.  There are several other files included in this volume,  I’ll list them below:
