Topic: Tips for Printing Parts that Fit Together

I'm a complete 3d printing noob.  Lately, I've printed several objects which are supposed to fit together (the glass bed holder, a minecraft figure I downloaded from thingiverse, and a minecraft chicken I made).  Every time I print it out, the parts require a fair bit of sanding or cutting to get them to fit into each other.

Are there some obvious things I'm doing wrong?  I'm just using default Slicer setting with Repetier-Host (0.3mm profile).  I'm still learning a lot, so I'm probably just missing something.  I hope it doesn't come down to trial and error.

If you are trying to get stuff to slot in, or slide against each other. I have found for my printer, that you need about 0.25mm-0.5mm tolerance. This was before I did some wall thickness calibration though.

Inside holes come out undersize.  Experiment with some small pieces to see how your machine needs to be compensated in the models.
