I dont find the original ball comfortable, this one is more suitable for full hand grip.
The rod has some nonstandart threads - 12x1.5 so i had to model it without nuts and metal threaded inserts.
PLA or PETG suggested + cooling
print 2 parts and glue together, grease before installing.
The part is already scaled properly in each direcrion, to compensate shrinkage and sagging, so if your printer is well calibrated, everything should fit snugly
