These work as advertised, but they're quite weak right at the transition to the main nozzle. I broke one during installation, which was a bit of a bummer. Definitely print extra. That being said, it was super nice to have these so I didn't have to feel like the whole tube of epoxy had to be used within 5 minutes of installing the single nozzle the tube came with.

This worked well for the JB Weld ClearWeld tube I had. The tubes that interface with the epoxy tube are very fragile and prone to breaking off in the epoxy tube when you're removing the nozzle. It isn't too hard to get them out if you have a pick on hand, but they definitely could be stronger. If they had a bit of a taper to them, getting them in and out of the epoxy syringe would be so much easier. Other than those minor complaints, I was super super happy I could just find and print a mixing nozzle for this epoxy. This saved me so much time!

Excellent print! My daughter loved having this for her Halloween costume! I used glow in the dark PLA for the blade and silk gold PLA for the rest. It was awesome. The only problem I had was the 1/4" dowel I used was too weak and the sword broke. Fortunately I was able to fix the sword with a 1/4" aluminum rod before Halloween, so it all worked out. My daughter definitely had the best Rumi sword of any of the many Rumis we saw.
