bowden fitting adapter (PC4-M6 to PC4-M10)

thingiverse

Installing the Bowden fitting adapter PC4-M6 to PC4-M10 is a straightforward process that enables you to connect your hotend's PC4-M10 fitting directly to the extruder side of your printer. This adapter is particularly useful when you're in a pinch and all you have on hand are spare PC4-M10 fittings, which can be a lifesaver if you're short on time or waiting for replacement parts to arrive - I know this from personal experience, as my CR-10's original fittings gave out quickly and I was left with only PC4-M10 aftermarket options. This adapter has been thoroughly tested on the CR-10 series of printers, and after printing, it requires a quick pass with a 2.0mm drill bit to ensure that there is enough room for smooth filament flow. For added peace of mind, consider using a brim when printing this adapter, but I was able to successfully print it without one.
