Introduction

Fastening parts can involve a variety of issus:

  • Parts need to go together and come apart
  • Parts print better in parts because of support needs or other issues, then need to be put together, perhaps permanently.
  • Parts are too big for printer.
  • Parts need only to go together once, the fastening is permanent.
  • Parts need to be assembled or disassembled without tools.
  • Cost is of importance.
  • Joints should/should not be visible.

Depending on the issues there are different methods that you may wish to apply.

How to Fasten

Nut and Bolts

Screws

There are a variety of screws that are "self taping". Given a starter hole ( drilled or printed ) you can screw into them. This is a pretty quick and easy way. Just insert the fastener and screw it in. It would be nice to have a reference to specific

  • screws
  • pilot hole sizes
  • plastic types and perhaps infill settings

This can also be done with a machine screw but the pilot needs to be quite close to the screw diameter and is relatively easily stripped. I have been successful with this, in one case with set screws.
