Onefinity CNC Z axis assembly acrylic prototype

I have a Onefinity Woodworker X50 CNC router, and have designed a new Z axis assembly that uses linear rails and guides. This design should be better able to support my water-cooled Jianken 2.2Kw ATC spindle.
I purchased the linear motion components from...
1) dy-global (ebay) IndustrialPartsShop in Korea, and
2) SYK in Taiwan
I had superb service from both these sources and highly recommend them.
The first part of the video shows the prototype mounting plates and components. The latter part of the video shows the machining (some examples) of the acrylic parts.
I used a 1/8" O-flute endmill from SpeTool for all toolpaths, except for a drilling operation with a Datron 4.2 mm drill. I have a variety of tooling from both these manufacturers and am always very pleased with the performance when machining wood, plastics, and aluminum (materials I predominantly work with).
