i bought a folgertech ft-6 and after a few prints i noticed that the original belt idler pulleys where not straight and where destroying the idler wheels. so i have designed this simple part that bolts to the frame and with a longer m5 bolt straightens the bolt up.
what is needed for mounting. 2 x printed stiffener 2 x m5x 35mm or longer bolts 6 x m5 locking nuts. 4 x washers
