Structural like this should be printed "solid" at higher end of temps and slow for best strength.
i was going to ask about the printing and slicing details, and the plan is to eventually share these sensor brackets so others can print them for their own conversions. for now, i'm just learning to model the parts and learning the best slicing and printing settings....
when you say "print solid", i assume you mean 100% fill. i adjusted the wall thickness up. i assume it is stronger to go with thinner walls when using 100% fill vs. thicker walls as the fill pattern is laid out in 90 degree rotated patterns while the walls are printed in the same direction. does it make sense to anneal the print afterwards? when you say print it hotter and slower, i assume that's so the new layer melts into the previous layer a bit deeper. would it be possible for you to share the cura settings you use for these sorts of parts?
i'm not sure if i should practice on PLA since i already have PLA loaded or if I should just load up some ASA and start printing it. i'm pretty sure any calibrationg i do with PLA won't apply to ASA or ABS. i'm trying to avoid having a bunch of old wet spools of filament around here. i'll probably need to figure out filament storage next.
