How do you accomodate for small openings? I’m designing a cam for a Halloween prop (That being one of the main reasons for building the printer), and want to use 1/4" square rod as the shaft…only by the time the printer’s done printing, it’s nowhere near that size. Likewise, I’ve attempted to print pieces that would have a captured nut, only to have the opening swell shut due to overextrusion.
Is this a PLA thing, or a calibration thing? Or do I just design with the expectation I’m going to have to drill holes to clean it up?
