Clough42's part cooling shroud...
As part of the aforementioned and quasi-ill-fated though educational retraction test, I added clough42's part cooling fan shroud.
I used the stretched version so as to be able to continue to use the existing MF HE cooling shroud.
After the 24mm test cube, this was my first print w/ ABS. Well..., actually..., I attempted this several times in a couple of situations, and got some ABS schooling. In the end, I added ears, and printed the part by itself rather than with a group of parts.
Apart from learning about ABS, some things didn't go according to plan.
Well..., one exception..., it did just work with the RUMBA..., no fussing around. Oh..., some of the spares that were shipped w/ my kit were handy. Like a spare fan!
But in every other way..., it was "interesting".
- I spent waaaaay too much time shuffling around town to try to find some metric stuff (drills). Gave up and made do.
- I got cocky with pronterface and ran my x-axis past x-max. Badness occurred..., but I gotta say, the high repairability of the printer actually made it easy to fix.
- Just the same..., an x-max limit switch is in this printer's near future.
- Discovered a problem w/ my y-limit switch and my y-bed in general. Will post on that in the future.
- When all was said and done, got completely the opposite results I was hoping for. I think that will be a good thing.
Per the previous post, gonna start the process of installing clough42's HE fan shroud. This will mean printing the standard length version of the part cooling shroud, as well as the new piece. As I recall..., I have to get a new fan as well..., so will research that a bit.
There are a couple of pottery related tools I want to make for use this week..., so the new-new shroud project may wait for that.

extruder cable support...
The extruder cable bundle was just bug'n me (and my X end-stop and RH Z rod).
Finally had a chance to do a complete "thing" from scratch. The jury is still out w/ FreeCAD, but it cooperated this time around.
I don't have the the swanky CAD skills of most of ya, but it works dammit!
Heh..., the irony was I told myself "no cable ties allowed". Ummm..., to hold a cable that is practically made out of cable ties. It was the principle of the thing!!!

first rationalization achieved!
Before I bought the Makerfarm kit, I made myself make a list of the things I would use the printer for, above and beyond printing printer parts or weird vases.
I can check off the first item on the list!
I hated the attachments that came with my current Panasonic vacuum cleaner.
The old Hoover attachments are a buh-zillion times better.
Thus, the Panasonic-Hoover vacuum attachment adapter was born.
This was a worthwhile little project for a couple of reasons:
It made me think a bit regarding the limitations of the material and FDM. There was a compromise between simplicity and having the thing I thought I really wanted. I really wanted a locking tab over the peg on the attachment, but that required a material flex in a fashion that it's usage basically didn't permit. I could have done it with two parts..., but I wanted a one part solution.
So..., I learned a bit more about FreeCAD. It still is a kind of buggy proposition, but it is definitely useful for certain things. Anyways, employing a taper (hence, using lofting) on the Hoover end solved the problem.
This was my first successful use of cold acetone vapor smoothing. For "utility" purposes, I'm quite happy.
I was sorta bemused when I checked out thingiverse for vacuum cleaner stuff. Jeez..., it's a whole sub-cult! The Pana-Hoov adapter will be my first contrib to thingiverse.
Finally..., while something like this is unbelievably mundane, I really feel that little things like this can serve two purposes regarding the notion of 3d printing for the masses: first, simple engagement with and appreciation of the things you use every day. second, it's a small step towards personal resiliency and ability.
It's the little things.
Dining Room Table Project...
(first: thx Dan..., will definitely check them out!)
I'm really happy with the way a recent project has turned out (and more than a little surprised that it actually worked out). This was the thing for which I've held up any additional modifications to the printer. It's also one of the things that served as "justification" (aka rationalization) for getting a 3d printer in the first place.

Next up for the printer: some mods, and then on to some things related to the art aspect of my pottery work.
