I'm starting to design everything I make around these brass insets. They're super handy and can be easily set into a PLA print using a soldering iron.

There isn't much to say about these, the fit and finish is nice and they work as intended for my application. A++ from me.

These. little critters are the only way to go if your printing upgrade or replacement parts for your printer. I always hated screwing into the plastic, just seemed wrong. I can go back and make all the parts be removeable and take them off and put them on all I want. (I tend to constantly look for the perfect setup on all 4 printers)BUY it, BUY it now!!

These work very well for heat-setting into 3D printed parts. The outer splines help to limit slippage in either direction and I've yet to have one break out when being tightened. I've gone through a ton of these and never had one with damaged threads, but it doesn't hurt to check each one before pressing it into a part.

These are different from ones i usually get. Had to adjust the diameter of the printed hole, but still work great.

These are great for 3D printed objects. The fact is has 2 directional knurles allow it to grab on and not slip out. Soldering iron on a good temp will set these easily. Will be buying more next time around!
