I received the disk and caliper a while ago, and decided to upload the .step file to JLCPCB, just to see their pricing. 5 days turnaround, 4 to 6 days shipping, 7075 alloy. 33 USD, boy, I would be charged more than that just for the material alone here locally.
I will post a review of the part  as soon as it arrives.

The cad file is supplied by RycaShawn, so i certainly expect it to be a direct fit.
I cannot imagine a CNC mill to produce anything that is more than a couple hundreths of a millimeter off, but time will tell. I will report back as soon as I have the finished article in my hands.

I received the bracket today, and the fit and finish is as expacted from a CNC milled part.
The time to make it was 5 days, as specified during the ordering process. Shipping was according to estimate at that time too, and the company handled the transfer through customs, so It could not be any easier.

The only place where the surface finish is different from what normally comes out of a CNC mill, is this face, which has the finish you get from a rotating vibrating sanding machine. This will take a polish with great ease too.

I am astounded how they can do it, in the time frame and at that bargain price.

And I wish I had the need for another smart bracket, I would not hesitate to order from this company again.
