Geeetech A30 Z Axis supports

Printed these at 0.2 layer height oriented as shown in photo with no supports. You'll need M5x30 long socket caps or button head fasteners to attach to the frame. Just remove the original bolts and replace with these. Also cut 2 pieces of M10 by 725mm long studding and fix with 8 M10 washers and nuts. Use an engineers square to true up your Z axis in relation to the Y framing and you'll be good to go!
