Login with my Xometry account hello, I’m designing a part with an FDM 3D printed hole to hold a 6mm wooden dowel, but I’m unsure about the actual fit due to print tolerances and material shrinkage. The hole is modeled at 6mm in CAD, but I know FDM printers often produce slightly smaller or irregular holes depending on factors like layer adhesion and filament type. For those who have tested similar setups, should I oversize the hole slightly to ensure a proper fit? If so, what diameter would you recommend to achieve either a snug slip fit or a light press fit without excessive post-processing?
Will a 6mm dowel fit in this hole?

Ejector pin placement near snap-fit
I’m working on a small injection-molded housing for an automotive sensor, using PA6 GF30. There are two snap-fit arms inside (cantilever type), about 2 mm-thick walls. I’m not sure where to place the ejector... read more

Printed bracket cracking – how to reinforce?
Hi, I'm prototyping a small bracket for holding a plastic cover in place—roughly 60 × 30 × 10 mm, with two hooks and two screw holes (M3) on the top side. I printed it in PLA with 20% infill... read more

0.4mm text in PLA
Hey all, my part needs to have perforated text on a thin PLA sheet, and the text is 0.4 mm thick. Do you think that’s wide enough to print cleanly without running into issues... read more
