If not could someone design one??.....Please haha

hem... just a little question : i know kapton is a heat resistant material... but are you sure it's also an isolant ?? I do not think Kapton prevent heat to pass through it....?

I'm actually running it from an external supply right now. Having it g-code controlled is a future mod ;-)

Slic3r has a screen to setup when exactly it should come on and I find that excellent.

I printed the two pieces bolted them together and snapped them on with a fan and all was good for about 8 to 10 hors of printing, then then fan fell off mid print. The clip piece had warped, probably from the heat. I printed a second one and about 8 hours later I had the same problem. I'm trying to remember what infill I used, 20% probably. I'll try and print a solid one this time around and see if that does the trick. The difference is amazing on prints that need a fan. The trick is to figure out when to turn it on and when to leave it off.

2n2r5's fan in the link above will take a fatter fan.

Excellent. I will give this a try tonight!

Impressive. Here's a noob question. What are the issues involved with private/open development like this and inclusion into the parent product as OEM? In other words, why doesn't Solidoodle incorporate such a clearly superior extruder into the product as standard equipment, assuming you the developer has no problem with that?

most likely its because solidoodle has already made a sizable investment in the "pretty" plexiglass extruder parts and would rather run through those first, while at the same time ironing out legal and monetary issues with the creator of the printable one (even if he says "i dont care, use it", it can still bite them later.) they have already stated, i forget where, that a printed extruder design is in the works. will probably be a derivative of this one.

I've finally gotten this so I'm happy with it. If you have printed 2n2r5's fan for the mk5, then there may not be much point in printing this.

2n2r5's fan:

http://www.soliforum.com/topic/3045/mk5 … -consumer/

This design is quite compact but the airflow from the fan is compromised as a result. It does do the job, however, and print quality is greatly improved when used at an appropriate time.

Instructions

Print parts at high infill for strength. No support needed. The fan shroud (ironically) prints a lot better with a fan. Therefore, you may like to print one, fit it and use it to print another, better quality shroud.

M3 x 10mm bolts to attach the accessory mount to the shroud.

Use a few layers of Kapton tape to protect the inside of the shroud from the heat of the extruder.

40mm fan should slip straight in.

Dimensions in mm.
