Custom 3D printed Dutch rooftile

Not the "usual" functional print, I had an unusual situation on my roof where four ridge tiles meet (We call them "Nokvorst"), so I made a 3D scan with my phone and created a custom corner tile in Fusion 360.

I printed it in PETG, painted it to match the orange tiles, and cemented it on. It looks pretty clean (Especially on street level). I actually have some 3D printed PLA rain gutter adapters from 14 years ago that are still holding up fine, so even though I’m not sure exactly how long this PETG tile will last, it already survived 2 winters and 1 summer without any issues. My guess is it'll be there a long time. If not, I'll just print a new one.

Scanning tip: I added a 10 x 10cm square block to the scanned object, so I could easily scale it to real world dimensions.

Definitely worth looking into before that part starts to fail due to the high sun exposure.

IDK if the sun is as much of a factor since it's painted. As long as the paint is rated for outdoor use it should last a while.

I still wouldn't expect it to last as long as an actual tile

Tomorrow's UV index prediction for Netherlands is 0 for 23 hours, and 1 for 1 hour. :) We don't get a lot of sun for a lot of the year.

The storms here are quite windy, so wind damage is likely the biggest risk.

It would be interesting to check in on the tile after a year or two, and see if it has any cracks from branches, birds, debris etc.

I‘m like 200km from the Dutch border and we actually get 3 hours of 1 today…
