    Excellent little gears, not perfect quality as the grub screws were at different angles (not 90 to each other) and there were minor surface defects but perfect for my needs and very lightweight so would work on any stepper motor, perfect for small scale CNC machines.

    fui a la paquetería por mi paquete pues estos nunca me la enviaron, aún así estoy feliz con esta pieza que me faltaba para mi proyecto , nomas que tengo duda que sea de aluminio pues está demasiado ligera y parece de plástico , pero ya veremos a la hora en que este trabaje

    The value for price is very good on these pulleys. I used them in my 3D-printed linear actuator project. Video can be found here:

    Ruined the goods, hypocritical Mr. Ida, "conscientiously": one of the wheels for some reason partially drilled 6 mm in diameter. Has spoilt the goods, d No id, is diligent": one of wheels what for particulate is drilled in 6 mm in diameter.

    Qualité géométrique moyenne. Perçage peu précis. Peux servir mais sur machine qui ne demande pas une grande précision, une cnc par exemple.

    è possibile che (solamente) questo pezzo sia stato inviato difettoso, mentre gli altri siano buoni; però, se una zona delicata come quella su cui scorre la cinghia dentata ha un difetto come quello evidenziato, può portare alla rottura della cinghia, e non è bello!
