Summary

Why would you want to have a plastic model of a hot end?

I wanted to have a model of a 3D-printer hot end for educational purposes in our Makerspace. I found the CR-10 Hot End Model by intoxikated, printed it and looked at it.

How I Designed This

Design process

            <div><p>I took the printed model and compared it to the real thing. What I was looking for was to show the inner workings of the hot end - but there was a lack of detail in the existing model.</p><p>So I threw away everything and as usual started in OpenSCAD.</p><p>The final model consists of 5 parts which can be printed in place or separately: the heatsink, the insert, the heater block, the nozzle and the lower end of the bowden tube.</p><p>Printing a cross section is enabled by default.</p></div>
