Thread Straightner A8
thingiverse
Couldn't find the nuts to make this out of steel so i printed it instead. Does a decent job of aligning the t8 rods. Tested with 25% infill and it did not twist apart. I would probably go with higher infill on the next one. Then just clamp it between two pieces of wood or whatever you have that is straight and solid, insert into drill and go in and out a few times. Excuse the goofy footing i made for it, needed to be strong enough to stay up while printing, will edit at some point but it was quick and dirty.
