Topic: Tolerances for 1mm hole
Hi all,
I have a delta printer with pretty decent calibration. I print with 1.75 ABS. Looking to see if anyone out there has experience printing an object with lots of tiny little holes. I'm looking to print cylindrical holes, 1mm in diameter by about 1.5mm deep. They would be part of a larger print and located in a section that is 100% infill. Ideally, they would be about 2mm apart from each other on all X/Y axis. To elaborate on intent: I want to sink these tiny 1mm diameter x 1mm long magnets into a solid slab of printing.
So the question is more on the design end. If you were going to make something like this, would you make the holes 1.5mm in diameter in the STL to account for expansion and any potential over extrusion? I have faith in my printer, but tolerances in most filament are not great for this type of high precision work, which means sooner or later int he print I'll get some over extrusion.
I'm typically a trial and error type of guy, but I have a feeling these prints are going to take forever. Looking for a second opinion on this one before I start.
