Will this work for the ender 5 and is the stock fan completely interchangeable with this one? Could you please share the link for the fan you used thank you.

does this work for the CR-10S?

So I printed it out and assembled it to test a G29 bed leveling routine. Its so thick that it is hitting my binder clips on the outside of the glass bed when I try to do it.

Is there any way to get a STEP or F3D file so that I could make a version that is a bit slimmer (ie removes almost all of the plate at the bottom)?

Hey! I have the same problem... Have you had any luck finding a solution for this? I would like to improve overhangs without hitting the paper clips. Thanks :)

Nope. I tried changing the model to remove most of the plate. I tried moving the ring up a millimeter. Did a few other things. It just never fully cleared the clips or parts (its so close to the nozzle tip height that it actually rubs on printed parts). Went back to using my old radial duct and I am currently printing out the Hero Me 2.

The Hero Me seems the best choice. Will it hit the paper clips though?
Thank you for your reply.

I really like this design. It's so much lower profile than the Petsfang design and leaves room for a BITouch switch.

Does this design only need the one extra screw. Does it otherwise use the stock screws?

I like your designs Carsten, but is there any chance of you uploading a picture of the blower at max doing a water dimple test.

If I'm calling it wrong the wrong name, here's instructions:
1) take a short plastic lid and fill it with water
2) put it under the hotend nozzle and lower the nozzle to just above the water surface
3) turn on the fan to max power
4) take a picture of where the dimple is formed in the water

A good blower design should have the dimple almost exactly under the nozzle.

Done. (for version 2).

Ive Printed this and I'm trying to install it but havnig an issue getting it to mount up I purchases the bolt for the upper arm but not sure what size scre I need for the inner connection to hold the fan in place. The stock screw are too short did you have to purchase another screw and a washer to hold the fan.

Thank You. It looks like its centered really well and is a good sized dimple even from that high up.

Exactly what I'm looking for. Any performance improvements over stock?

with that 5015 you're going to get more air being pushed at the same power level while being quieter usually. Means better cooling.
