Fix the broken thread insert on my ring light
These fixed a broken brass insert for my ring light. Perfect fit and size. Good grip in the plastic but added some super glue to make sure it was secure. The thread is exactly what I needed for all of my tripod mounts. Functions great. Easy to use and good quality.

Simple and Perfect
Hot brass go in the 3D print, cold brass no come out. Used for a homebuild with soldering iron install into PETG with absolutely no issue. Perfect fit, threading, and quality.

Perfect for DIY projects and 3D prints!
These worked fantastic with my heat press! They fit a standard camera mount. I personally used them for a DIY SteamVR tracker project with a 3D print and they are shockingly durable!

Solid inserts that handled my needs.
I needed to 3D print some items that mounted to a tripod using a 1/4-20 screw. This worked great for my application. They seem to hold up well with polylactic acid (PLA) plastic parts. You'll be fine with these for hobby applications.

If you 3D print and need a way to put screws in your products, these are for you. I had a full set of these of varying lengths and screw diameters (2, 3, 4 mm) but I used so many of the 3mm size, I ran out!! so I was very pleased I could buy JUST the 3mm and not a complete package.
