Can you guys please send me paypal invoice for a new hobed bolt ? One that came with the printer turned out to be cut uneven, causing waves in layers. I replace it with one i bought on ebay but it came with bad recess cut. One cut was slightly overlapping the last cut so filament would skip. I need another hobbed bolt and i dont know where to get the right one. Ebay has ton of them but only few of them have correct lenght. Thanks !
