Cohjoy Prints · Parts

Parts nobody makes anymore.

A knob that snapped, a cap that fell off, a bracket the maker stopped selling. Send a photo of the broken one or its twin; we measure from the photo, draw it, print a test fit, then the part. Every part we solve gets a page here, so the next person with the same problem finds it.

• From a photoLay the part on a sheet of paper and shoot straight down. Our CJm sheet turns that into millimeters.
• Test fit firstA quick ring or shell prints first and gets checked against the original before the real part.
• The right plasticPETG for sun and heat, PLA indoors, TPU where it has to flex. The quote says which and why.
