I don't have one but I have considered buying one in the past. My problem is that I've not touched a metal lathe since shop class in the 8th grade. If I can't find something off-the-shelf I may take the parts to a local machine shop and see if they can make it work. If the threaded axle was cut down to 135mm by taking 3.5mm off each end, and the two end nuts were "shaved" down by 3.5mm each, the entire assembly would fit and then using a 12 x 135mm thru axle to QR adapter (these seem to be pretty common) it should work.
Any thought on why this wouldn't work?
