25% infill strong enough?

I am working on replacing all the PLA parts in my "Sturdy" with ABS parts. Sliced the fixing blocks and didn't realize I had forgotten to re-set the infill to 90% so my blocks printed out at 25% infill (rectilinear pattern). I hate to waste the plastic, but would fixing blocks at 25% infill be strong enough to use?

Hi,

I really depends on whether you added additional shells. If you have then you are probably safe but if you only have one shell then you would need to be careful not to overtighten the screws.

I believe there are two shells around the holes. At least, the nozzle goes around each one twice. I sliced them at .3mm layer height with a .4mm nozzle.

Ha, I have a set put aside where I did the same, only 25% and one shell. I think they will work if you don't over tighten the screws. You might as well try them as they are easy to replace if they break.
