One week ago i got my Geeetech A30 (insider tip) and now want to upgrade things.
Ive printed new knobs from mazzoca and than realized that i got a newer version of the A30 with bigger knobs from factory which didnt fit to the print.
... view hours later i designed & remixed & printed the new knobs and here you have it!!
So if you want to upgrade knobs, you should first take a look and decide which knobs you need
thnx and have fun
Update: installation: Flip the original Knob and set the Adapter on top, should fit perfectly
and the spring does not have to be stretched so much
