Design advice (engineering) for beginners

Quote:

If you need accuracy on the holes, always design the holes with a slightly smaller diameter and plan to re-drill.

Or just print them the size you want. If you know your printer, that's the best option. Redrilling always has the chance of chenging the bexact centre of the hole. So just make it the size you want in the first place.

Also some of the things he says are obviously printer and slicer dependant. Most of the curves he says are bad, I could print with no problems.
