DX Commander N Connector Conversion Cover

prusaprinters

DX Commander ground plates come with a UHF connector and recommendations for how to waterproof that thing. This should help remove some of those extra steps, though waterproofing the connections between radials and elements and their respective plates and screws still needs to be done. I decided i wanted to replace my UHF female with a N type female connector and had one with a screw-through flange on it. I designed up the cover you see here to fit on the backside of the ground plate flange and that connector, provide the threaded inserts to connect them together, cover the pigtail connection and provide a place to anchor some more heat shrink. I decided to put the N type connector in from the backside of the flange. That causes some challenges in installing everything but does better cover that interface from the elements.I printed this “on its tail” in 3DXtech ASA filament without support. I used my enclosed franken-ender 5 using rails and an H2 high temp extruder, running on Mainsail / Klipper. This model definitely benefited from the new Arachne perimeter option in PS 2.5 alpha 3. My print settings:3mm skirt0.6 nozzle0.2 layer height in the slated section to improve the overhangs without support0.3 layer height at the tail and in the straight section4 perimeters50% adaptive cubic infillInfill firstInner perimeters first8mm^3 volumetric flow limit50% first layer speed20% outer perimeter speed (again to help with overhangs)12% infill/perimeter overlap Cautions:Yes, i'm still tuning pressure advance on my printer. The pictures show dimples in the prints at the seams because apparently I still have it set too high from when I was printing PETG with a smaller steel nozzle.This used M3 x 5.7mm long threaded inserts in a set I have. Your inserts may varyThe holes for inserts fit the hole spacing on my N type connector @ 18mm center-to-center dimensions. Your connector may varyThe cut-out in the bottom of this model fit the center wire connection on my N type connector. Your connector may vary. Even for mine, this is tight on the pigtail connection. Future edits may lengthen / widen that cutout to allow easier installation.
