roof plate for Duplicator 4 with allowance for mk9 extruders slightly higher mechanism I forgot AC3D has no really world measurements so the original file here is a tenth of the correct size. You can scale this file or download the x10 file which should be the correct size already Dimensions are 72 x 54.6 x 7mmprint. fit. You might want to ream the holes with a 3mm and a 6mm drill before fitting depending how accurate your printer is on holes.
