This is not a real Remix of the K8400 hatch door parts, but as I could not add my DXF file for the door laser cut to my make, i decided to publish this as a Remix.
I used this file to laser cut the door from 4 mm PMMA.
Hope this file helps others wo want to cut or CNC mill the front door.
It's designed with the door stops in mind, if you don't use these an want a tighter fit you have to offset the outline about 1 mm.
I took the Velleman K8400 3D design files from Github and used the front panel STP as the basis. Then projected it to 2D in Fusion 360 and the final adjustments were made in QCAD to fit the door (had to shrink it) and place the mounting holes
