Anet A8 Y Front Frame Original Size

Update 1: The 4 rectangular holes are now 0,5mm bigger. I make a test print and had to re-grind the holes a little bit

I want to create a new Front Y-Frame - because i am using a "Cable-Chain under the Hotbed" and the Frame-Stabilizer i found did not work with it.

So at first i create Y-Frame with "original" Dimensions:

Distance between outer holes: 218,5mm (for threaded rods)
Outer Holes from Desk: 22,9mm
Distance between inner holes: 171mm
inner holes from Desk: 40mm
Thick: 8mm
