A good tolerance for a cup holder designed with 1/2" EMT would be about 0.8mm, to allow for good fit but not compromise structural integrity.

whats an emt? I tend to go for .5mm tollerances to start but it also depends on your printer.

[primal parrot]

It’s electrical conduit.

[primal parrot]

Yes the 0.8 was to much

[primal parrot]

0.8 was too much 0.5 worked much better

[copper pond]

good, to hear. depending on the project if I want a really tight fit I would warm up the print in some warm water and test fit it.

im trying to lines thses up and use the holes to drill threw the part under it

[tepid wyvern]

What are you trying to accomplish with the drawing? Usually drawings are only for marking dimensions, etc. You edit the part or assembly.

[tepid wyvern]

That looks like a task in the part studio

[primal parrot]
