Lowrance HDS / Elite port caps

Stops spray, dust and fishing-trip grime getting into the empty sockets on the back of your Lowrance unit. You get four caps, each with its label on top (PWR, N2K, ETH, XDCR) and a ribbed plug that grips. Change the socket sizes to match your own unit.

Notes
The inside ceiling is a cone, so no supports are needed. PETG or TPU 95A also work if you want caps that survive the sun better or grip more softly.

Assembly

  1. Push each cap straight onto its matching port until it bottoms out.
  2. To take it off, pull it straight back using the ribbed grip.

Good to know

  • Port sizes are estimates. Measure each socket across the outside and set it on the Adjust tab before printing, or the caps may be loose or not fit.
  • If a cap is too loose or too tight, change the Rib grip slider by about 0.1 mm and reprint. PLA doesn't stretch, so start gentle.
  • These are dust and spray covers, not waterproof seals, and PLA can soften in a hot boat, so pick PETG or ASA for the dash.
