Ruthex inserts... what else is there to say, they are the leader for 3D print inserts
Ruthex, the best holding force for 3D printed parts I've tested/used. Everything from PLA to PPS-CF. Quality is always great.

Next level of 3d printing
I've never had any trouble setting these with my soldering iron. I don't use any additional tools, jigs, or presses. Pretty easy stuffThey work well and don't come out. Big fan
User
Secure and consistent quality
These are a more secure design than the ones with vertical ridges. They are easy to guide in with my soldering iron, and I've never had any issues with rough threads.

Ideaal voor 3D printen en met soldeerbout smelt je de schroefdraadbus er zo in.

Impeccable pour l'impression 3D
Utilisés pour insérer dans les impressions 3D en PLA ou ASA.Une fois mis en place ils ne bougent plus et permettent un très bon serrage des pièces.
