Best 3D printed part cooler for stock hotend?

[JanZurLok]

Hi everyone,

I own a Geeetech A10 from 2019 and are relatively happy with it. I mostly print PLA sometime PETG and for this the stock hotend is doing a good job.

However, I do have some problems with the overhangs bending up on certain positions, this sometimes ruins prints in PLA.
I do think that the cooling is the biggest problem there, and I do not like the way the A10 part cooler ist built.

If found some solutions on thingiverse however, they are mostly for the E6D full-metal hotend and I have heard that that hotend will not be an improvement for PLA prints in comparision with the stock one.

Here is what I'v found:

Petsfang for A30 (should fit the A10 as well)

This only seems to work for the E6D hotend and not for the stock version

This is made for the stock hotend, however in my printer is a rectangular stockend - so there seem to be at least two different version for A10 hotends

This supposedly has a stock hotend version, however it is not mentioned which one - and I guess it is for a roundish hotend...

So my questions:
Does anyone know how many "stock" hotends are exist for the A10?
(Mine looks like this: https://www.geeetech.com/geeetech-a10-a ... -1041.html)
Has anyone fitted his stock hotend in above mentioned part coolers?
Has anyone found or made a good (similar to the above) part cooler for the Geeetech A10 with the rectangular hotend?


Thanks for any help.

Best,
Jan
