Duender FT EMS Panel for Electronics

EMS Panel [Edit: The overall dimensions of the panel have been adjusted to give a better fitment. The original version was too tight, although with some effort it could be forced into place. I have also extended the tabs so that they bolt into the top V-slot which makes it a much easier task.] This is an EMS panel for the Duender 3D printer. What is EMS? It is a system for managing the electronics for 3D printers from FizzyTechs. It consists of a panel with hexagon cutouts, a set of hexagon shaped plugs that fit into the panel, and a repository of mounts for various 3D printer electrical components. The idea is that if you replace a component, or need to move one around, you can just print the mount for the new component, or move the plugs to a different cutout. There are also plugs for zip-ties, and a set of cable ducts for solving any cable management issue. https://www.printables.com/model/558357-ft-ems-mounts-repository Not that there is no upper lid for the electronics bay, I was thinking a sheet of Acrylic with a cutout or two for fans. The hexagon holes in the EMS panel will allow cooling air to pass out from underneath the Duender. Printing Print with the flat side down, it should import in the correct orientation. No supports are necessary. There are some bridges, but they should print OK provided you have some part cooling enabled. The model is 288x249 so you will need a printer capable of 300mm. You can use the slicer to split it into 4 parts, then super glue it back together. There are “dog-bone” joiners available for EMS if gluing is not strong enough. The dimensions should give you 1mm gap in both directions, however filament shrinkage could cause more gap. So it's best to calibrate the shrinkage for your filament and set that in the slicer before printing. Installation The panel mounts in the bottom of the rectangle formed by the 4040 extrusions in the base of the Duender. Your electronics mounts to the base using the plugs and adapter mounts from the FT EMS repository. I suggest working out the electronics component placement while the EMS base is not installed, as it will be easier to make adjustments. Once you have worked out the positions, remove the components from the mounts, install the panel and re-install the components. Use 8 sets of M5x8 bolt and M8 T-nut (should have a bunch available from the corner bracket packs) to bolt it to the lower V-slot. The EMS base should be flush with the bottom of the 4040 extrusions, and should clear the Z-axis steppers if you didn't space them any lower. CAD The part is designed using FreeCAD. I can't provide STEP files, sorry, as FreeCAD can only import STEP files, it cannot export them as far as I know.
