Plastic in mine oil dipstick just broke off, so here is my handle from petg.
You can use HTPLA, there is no bigger temperature than 98 Celsius degrees.
Why oceanblue PETG? It's the only non PLA plastic, that I have now.
As you like, but 15% is ok
- After printing, remove thin support with knife.
- I used 6 nails to connect two parts. If You have nice 3D printer, you can use filament to do that. (mine is making smaller holes)
- The glue is not needed, a handle fits snugly in the oil tube.
