MPX Bulkhead Mount

thingiverse

A week or so ago, I posted about creating a XT60 bulkhead mount and was asked if I could make something similar for an MPX style connector. I ordered a 10-pack and as soon as they arrived, I modeled them in 3D and then created a bulkhead fitting and attach flange. The connector fit snugly into the fitting, so I modeled the attach flange opening slightly larger to make installation easier. The design requires four 3MM Flat Head fasteners. The ones shown are the only ones I had available, so I'll be stocking up. The bulkhead fitting is threaded for a 3MM fastener and the bonding procedure involves cutting a rectangular hole in the proper thickness material and placing it between the attach flange and the fitting. The connector can then be pressed in. I was able to get a tight fit on my first try, but if yours comes out too large or too small, adjusting the scale of the print can compensate. Once the connector is pressed all the way through and flush with the attach flange, a drop of CA on each side of the fitting will secure it in place. Don't use too much, as you might make a permanent attachment to the flange or spacer. I plan to use this fitting to connect aileron and flap servos. The fitting will be attached to the wing root rib and mate with the male connector attached to the receiver in the model fuselage. Printer settings: I used an HICTOP printer, with no rafts or supports. The resolution was set at 0.0625 mm Z, and infill was 50%. To print the fitting correctly, it needs to be face down due to its hollow design. The flange should be printed face up because of the countersunk fastener holes. I printed two at a time to allow each one to cool between layers.
