Fusion 360 designs of the enclosure panels may be found in zip file on Thingiverse.
Design files have several parametric values which may be adjusted to fit you specific requirements:
- XRailLength – length of X linear rod
- YRailLength – length of the Y linear rod
- WallThickness – panel thicknes
- PrintHeight – Printing height of the 3d printer
By default those values are for 350mm linear rods 5mm thick panels and 300mm printing height. So if you want to use 8mm thick material instead change WallThickness to be 8mm in all designs which use WallThickness so the design will adjust.
