Tired of having a 3d print fail over and over? Frustrated that the printer just never works?Maybe it's just the design!
Don't take offence, we're not citicizing your design skills. Fact is, there are certain shapes out there that might seem simple, but just end up being really hard to 3d print. If you're designing a part that will initially be printed (the final version might be cast, machined, etc.), it would be prudent to design your part in a way that will work well for both the prototype and the final version.
