Using Bolt Inserts in 3D printed objects

I assembled the 3D printed camera today. I used the fittings I got last week. It turned out to be quite straightforward. I popped the special tip on the iron and set the temperature as low as possible (200 degrees). Then I picked up the fitting with a pair of pliers, popped it on the end of the tip and pushed the fitting into the hole in the 3D printed camera body.

Above you can see the result. I can now screw a bolt into this fitting to hold the lens in place. This is a really great way to screw things together. I’ve had a lot of success just using bolts in 3d printed holes, but this should be stronger and won’t wear out if I need to remove and replace the bolts.

This is the finished fitting in place with the lens attached. It turns out to look quite tidy. Next thing to do is make the handle and then take some pictures.
