Just in case you have the push in nuts.

Cool, perhaps you could sell inserts or have the option of you inserting them? Perhaps even sell them assembled?

I am about ready to print the last piece of the LR4 which for me is the core. I think I am going for the regular one.

I printed out the test block and the hole seems a bit large for the M5 inserts I have. Did you use a specific insert when you created this?

Thanks!

I used generic ones and cnc kitchen.

Are you sure you went deep enough?

I only did a cold fit so far thinking the insert would be flush with the insertion side. The knurled end of the insert fits in the hole which just seemed different than what I’m used to for heat set inserts. And the ones I’m using have the same dimensions as those from cnc kitchen. Did you go deeper? Thanks!

Yes. Look in the hole you will see a tapered section then a shoulder, you push until the shoulder.

The top holes are pretty deep, the bottom holes are not very deep and easy to see the shoulder.

Thanks Ryan. I see the shoulder and will move forward with this info. Cheers!

Heat set inserts are awesome. I’ve found I’ve been using them more and more in projects.

I printed my new core and have the heat set inserts installed and ready to go. On the Printables page for the design Ryan suggested putting in an m5 screw as soon as possible so that the inserts cool straight. I took that advice to another level by inserting a 40mm long m5 hex bolt first, attaching the insert to that bolt with just a thread or two, and then using my soldering iron and insert tip to heat and push the insert in. That forces it to go in straight relative to the 5mm hole on the tool holder side. I used a blue permanent marker to make a ring around the bolt about a half inch from the bolt tip, and used that as a guide for pushing the inserts to a consistent depth. Once I saw the blue ring peeking through the tool holder side I stopped pushing the insert into the core body. That worked great for me!

Good thinking, I like that idea!
