UPDATE: We've improved the head attachment system (Patreon)

Hi again,You can see how the new system works.  

From the neck side it is still the same ball, and from the head side there is now a span pin. Insert the pin until it clicks into the head and now the head will be securely held on the pin. If model has several heads you need to print the same number of pins as the heads.

And another thing is you need to print the pin in horizontal position using auto supports. In this case the pin turns on quite durable. 

We're going to change all our previous models to this system over time. You can leave in the comments your suggestions which models we should redo first.

We are sure, that many of you can set auto supports but just in case we'd like to show you how we do it in Prusa Slicer

The pin has a horizontal position (orientation).

Then we set support material (right click on the pin and then click on Support Material). Then click on the Generate support material check box.

And after slicing we get these supports.

Can't wait to hear your thoughts on this improvement and know what you'll get. And also which models we should redo first.Thank you for your support!With lots of love and hugs 💜💜💜Svetlana and Dmitry
