New Discovery

One of the hollow structure issues we've had in the past with 3D printing is trying to tap a thread into a hole. It often works, but then often it doesn't and when it doesn't the hole breaks away and we have to print the print again. In this case I have added some PVA glue part way though the print (handy being able to pause a print anytime!), hence strengthening the hole structure. Seems to work well so far.
