Welcome to the SeeMeCNC Community

I received an STL last night from @PartsDaddy for the EzFan Shroud. It clips on to the standoffs on the standard Rostock Hot end. The purpose is to cool the peek (the plastic part above the business end of the head). This ABS shroud is an extra insurance policy against heat creep - giving you potentially a jammed PFTE tube in the head. [Edited with forum feedback, thanks folks!]

Note: This is not designed to cool PLA so that you don't get slumping. That part you can do with other fan shrouds. Also, due to temps around the stock hot end, you should print this with ABS.

To use it, get a 25mm x 25mm x 10mm fan that @SeeMeCNC sells for $5.00 here:

The STL for this is here:

Now, proper credit should also go to MHackney for his kicka$$ Kisslicer settings.

I used .2mm layers. The only changes I made were:

3 Loops
.25 Infill
Extrusion Widths(all): .53MM
No support
Head Temp 240, Bed Temp 70, printed on glass with Elmers Washable Glue Stick
Fast settings: 8

I didn't center it. This was my first print with the new heat cartridges, stock SeeMeCNC head, Tricklaser arms with lash straps, and tuned with Geneb's docs.

I don't have a fan yet or I would show you that!

I'm confused.

What is this for?

From the Github, the S3 Beta fanshroud is for the S3 All Metal BETA Hotend testing. This HotEnd only
seems to work with ABS, Nylon, HIPS, but not PLA well yet.

Wrong one I believe Carl, I think it's this one:

the 70766 fan shroud is for the SeeMeCNC Hot End and a Rostock MAX.
Made to use a 25mm x25mm x 10mm fan
Mounts to Rostock/RostockMAX Platform

I printed mine out yesterday. I'd forgotten how much of a pain ABS can be.

Interestingly enough, I ran the SeeMeCNC Silver ABS I had at 205. Extruded perfectly. My stock hot end has a thermistor that's verified against a thermocouple to be within 2-3 degrees of the set point.

I believe you are correct Neal, it was a little confusing when I read it.

Darnit...in my haste and exhuberence... Editing and including info so it's at the top of the read...

Thanks for the extra info for those of us who are a little slow
