@moccasin Printing something like this Is a challenge. First off forget about PLA as if you run hot water through it that just might deform it Now ABS and PETG are tougher but IDK how you printed it a part like that should be printed with enough perimeters to make a solid part. The ideal material for something like that probably would be Nylon like a Taulman 910 or a CX12 from Hobby King. Both are Hard nylons and if you print them right then they will rather deform than break we put some 910 and CX12 parts in the vice and smashed them with a 5lb sledge hammer just to see if we get layer separation - we bent the part 90 degress but did not get it to break So I think that might be your best bet for a 3dp solution.
