Is the Bracket.svg, dated 9. Jan., the extended length that reaches the original waste-board? I remember there was a chat about it on the FB group.

Keep up the good work!

The two support arms are dated 1/9 and include the deeper magnet holes to support 6x4mm magnets. Previous versions used 6x3mm magnets.
I haven't uploaded the new metal brackets design. I certainly can. It is the upper track brackets made out of steel with the 7 "accessory" holes on the side. These can be used instead of the acrylic brackets + stabilizer bracket.
Suppose you could cut the metal bracket design out of thicker acrylic, but the stabilizer bracket is incompatible with it. The metal brackets are also a lot longer so they'd wobble like heck if made from acrylic.
You could carve them out of aluminum... During my prototype testing strength-wise, Aluminum is roughly half way between steel and acrylic, in this use case.

Well, I for one would greatly appreciate if you would make the file available. I might even get it done in steel elsewhere.

Done ;-)
You'll find both the svg and step files for the new Steel Brackets, in this thing, if you'd like to have them made for yourself. In the next few days I'll have them available on my website for purchase in a set of 2. Only 100 pairs will be available from this initial order. I will order more as soon as possible.

What are the dimensions of those brackets? They don't import into anything with dimensions that make sense (unless they're MEANT to be a fraction of a mm in size...)

The brackets are nearly 9" long and roughly 2" wide. I was importing them into Carbide Create to cut out. Both brackets are identical so just import the Bracket.svg twice and arrange as needed.

Cool! That lets me know what I should be looking for. I kept trying to import them into CC and Vectric and getting really WEIRD numbers. I'll fiddle. Thanks again!

I downloaded/imported the svg into my Carbide Create... here's a screenshot of the result with exact dimensions.

Brilliant! Perfect! I wound up importing the DXF (I'm not sure where I got the DXF?) into Solidworks, and got the same dimensions as you have shown. I then exported and imported into Lightburn with the right dimensions for the laser cutter here.

Does your design not include the two brackets that mount to the gantry? The boot and these "L" brackets would seem to be of no use without the brackets that attach to the gantry. Am I missing something? Thanks!

The two clear top parts are cut out of acrylic. The SVG file is included so you can carve those out of 3/8" acrylic. For this bracketing system, Acrylic was the stronger choice than 3d printing them as well.

Awesome! Thanks, I'm looking forward to trying it out!
