Ignition key weather cover Volvo Penta

thingiverse

As I'm renewing the engine control panel of a Volvo Penta equipped sailing boat, I thought to make a weather cover for the ignition key. On smaller boat the engine control panel might be too exposed to weather elements (=rain), and moisture might enter the ignition key mechanism. I've also seen few fellow boater who have big issues with engine electricity and the ignition key. The inner diameter of this little cover is: 42.4mm The Volvo Penta ignition key block has outer diameter of: 42mm This is my first model where the filament is changed! Worked very nicely! On the Cura, rotate the model 180 degrees, so that the key points up. The slice the model. Use the replay slider to find out the layer where key appears for the first time. In my case that was the layer 91. Then go to: Extensions -> Post processing -> modify G-code -> Add script and select filament change. Enter the layer where key is seen for the first time. Then slice again and print. On the printer, do the filament change as instructed. To my big surprise model needed no support and printed nicely.
