I’m completely new to CNC milling and also to CAD and vector graphics. While waiting for the Nomad 3 to ship, I got busy learning inkscape and FreeCAD. Once my Nomad 3 arrived and I found the surprise BitZero v2 in the box, I realized the beginner tool tray video from Winston that I carefully studied would have to be modified. This is the result just after vacuuming it:
I followed Winston’s advice and used the Amana 46200-K downcut mill which yielded a very clean surface finish; no sanding required. I also put the plastic fan on the collet nut which helped keep the pockets cleaner while using the downcut mill.
Just in case this could be useful to others, here’s the svg file that I created and imported into Carbide Create. Pockets and Contours were done just like the original tool tray instructions.
If I were to redo this project again, I’d make one of the lower channels wider so both wrenches would go into a single channel together as I always use them as a pair. Then make the other channel to fit the allen wrench used for securing the waste board.
I made a much less refined version of this sort of thing.
For the wrenches, I decided not to make grooves or a tray, but instead left it it flat and put two 6mm holes per wrench, and then glued a magnet in each hole. This keeps them in place on a flat surface. I found this easier to grab and replace than digging them out of a recessed tray.
Nope. I scanned them, imported the images into CC, scaled them, then did a lot of ‘tweaking’ to get the shape correct - and a lot of help from @WillAdams!
I’m not sure if the “new” Nomad 3 wrenches changed? The spindle retaining wrench I received with my Nomad 3 is quite loose with ~2mm of slop in it. It works, just.
Sure Will, I’ve emailed support regarding my oversized spindle wrench.
I do have good set of digital calipers.
Spindle shaft flats are 12.0mm apart
Spindle wrench throat is 13.3mm wide
For comparison, the collet nut is 17.1mm wide and the wrench is 17.4mm wide.
I measured both wrenches at the flat of the throat opening. The bottom of the wrench throat tapered down 0.1mm from the top measurement on both wrenches.
