What a year. Read and remember the biggest moments of 2012.
And at the end get to know of a completely new product, the best way to finish a year.
Achievements in 2012
Just a quick recap before we advance to the next big thing:)
Arcol.hu hotend v4 — 2012 January
Although the initial version of the v4 hotend went live at the end of 2011, many later improvements came this year. So it is a really 2012 product. Grab one here.
Arcol.hu hyena v1.0 — 2012 April
I started with v1.0, do you remember?:
M8 nut with M3 grubscrew — 2012 April
Arcol.hu hotend v4.0.5 — 2012 May
Bugfix release over v4.0. Announcement here.
Grooved 608 bearing — 2012 May
Tiny, but useful improvement. Original announcement here.
Arcol.hu mini hyena v1.0 — 2012 June
Discovering the need a reliable drive gear for direct drive mechanism, I launched the mini hyena campaign.
I gathered many feedbacks from this campaign, which helped to redesign the whole hyena family. See at the end of this article:)
Arcol.hu hotend v4.1.1 — 2012 October
Arcol.hu hyena v1.1 — 2012 October
Spring kit — 2012 November
Maglev fans — 2012 November
Maglev fans move more air with less noise; a small but nice improvement.
It is available for sale with the complete extruder (see next point).
Complete extruder — 2012 December
The Hyena family v2
Asymmetric tooth profile - Hyena v2
To come up with this tooth profile it had taken countless hours and numerous versions.
The v2 outperforms v1 by 220%. That means at a given force where v1 has already slipped and chewed up your filament, v2 is still pushing it through happily!
One of the main discoveries from the campaign was
that the four different sizes did more confusion than good.
The conclusion is to make one size with either a 5mm or 8mm bore.
It makes everyone's life easier and one size fits all!
Regular hyena adjusted — Hyena v2.0
The shorter, the better
One size fits all
A picture worth a thousand words:)
Mini hyena fits on either 5mm or 8mm motor shafts.
When the extruder is properly set up the hyena accumulates absolutely no plastic chips over time.
If there are some chips inside, clean the Hyena with a needle not a file.
Never use heat especially not a blowtorch.
I should compile an another article, where we are currently quality-wise, since I teamed up with a professional graphic artist (hey QNLaca!:)).
Hall of fame
People, who made the mini hyena and also the v2 development possible:

I change slightly the commenting policy. I will close the commenting after a week of the date of publishing to prevent spams leaking through.
But in all occasion, please prefer the mailing list.
After the above deadline, any further discussion can only happen on the mailing list, in this thread.
