Spool Arm for P3Steel

I downloaded a spool holder that slid over the top of my P3Steel however this reduces the MAX height of the Z axis and its also prone to wobbling and moving so I designed this to fit to the top of the printer with one M3 screw per side, it does not flex or move and it also is flush on the other side

V2 has now been added. it is now easier to print in ABS as I have removed the small tab with the hole in it and made the arm thicker, the screw now goes through the center of the arm with a m3 nut
