Aviation Connector Cover (Parametric)

Fully parametric: adjust the dimensions for the coupling nut, plug shell, and wire entry to suit your setup. Ideal for protecting exposed plugs or tidying up cable ends. Default sizing fits common GX16‑style connectors. Easy to adapt for other connector sizes — just tweak the parameters. Prints well in PETG and TPU 95A. If printing in TPU, it’s best to invert the model so the supports form on the outside. Why I Made ThisI designed this cover to protect the aviation connectors on the fuse box of my boat. The connectors sit in a spot where they could be exposed to moisture, dust, and the occasional splash, so I wanted a simple way to enclose them without changing the wiring. Printing the cover in TPU gives it a bit of flexibility and adds extra protection from the elements, while still fitting securely over the connector body. If you have a similar setup — especially in marine or outdoor environments — this cover can help keep things tidy and shielded.Tips & Common IssuesClean print bedM
