Shorter Powerpole Duplex Panel Mount with Screwtop and No Flange

This model is a shorter version of the panel or bulkhead fitting for two anderson 45A powerpole pairs.  It is sized to fit in a 33mm hole in an panel up to 6mm thick.  A cap is provided for protection when not in use.  This version does not have a flange for mounting, using two nuts instead.  This may make mounting easier in some instances.

Components should be printed in their native orientation. The Body model should be printed using supports from the build plate.  There are two versions of the Cap  model. One is ribbed for an easier grip the other is smooth.  Print 2 copies of the Nut model.

Print with a layer height of 0.2mm or less for best results with the threads.

The threads are nominally M33x2.  You may need to gradually work them in after printing to smooth them out, depending on your printer.  The socket for the powerpole pair has ribs to retain the pairs.  There is also a provision for pinning the pairs in place with a length of 1.75 filament or a 2mm pin.  You may need to chase the hole with a 2mm drill for easier passage.   

Powerpole pairs may be easier to insert if individual pieces are slightly offset to allow one side to engage the rib before the other.  As the first piece engages the rib it allows a bit more room for the other piece to get by the opposite rib.   If the pair is difficult to snap into place, you can lightly trim the retaining ribs in the socket to ease assembly.  If you trim too much, just use the "pin in place" option.

When installing, you will probably want to use a small bead or fillet of RTV or silicon sealant to improve waterproofing.
