We took a trip to San Francisco to meet up with @KarlMeyer and put his 3D printing knowledge to the test! On this episode of #PrintFixFriday, we’re showing off one of the largest @bondtechab INDX Founders Edition prints ever made: a massive, 233% scale, 8-color printed INDX toolhead which filled up the @Prusa3D CORE One's build volume. This epic 3-day print required over 4,700 tool changes!

But it wasn’t an easy journey. We ran into a massive clog on nozzle 6, forcing us to perform a manual nylon cold pull using PA12 nylon from @polarfilament to clear out a CHT nozzle. We also tested multi-colored fidget cubes with over 870 tool changes, which led to cooling, overextrusion, and software slicing issues.

Are these multi-color prints a success or a technical failure? Watch as we break down the hardware vs. software bugs on the Bondtech INDX and share how to get your prints looking perfect.

Would you consider this INDX print of an INDX a fail? Let us know in the comments!
