So, I'm bored. I'm waiting for new filament, and some new equipment, and I have nothing to do in the meantime. Actually, that's not true. I have study I should be getting on with and I have (to a certain degree), but I've gotten bored with that too, so I've spent a good portion of the last couple of days actively procrastinating. Which is completely unproductive, and a great way to get me to procrastinate more. So, what the hey, I'm going to print out some more bits for the console. Not strictly speaking necessary until I get the new filament, but at least it will make the prototype console look finished.

The interior of the rotor was going to be printed from a clear PLA filament, similar to the same stuff I traditionally have printed roundels from. But I'd run out of it, and so wasn't planning on doing anything else. But, as previously mentioned, I'm bored; nuff said...?  ::)

Anyway, while rummaging around in my box of filament spools, I found this:



... which may be darker than the clear I've used in the past, but hey, it'll do in a pinch! I'd also forgotten I had it, a completely untouched spool of Clear Grey. In fairness, I did inherit a lot of spare PLA filament when my brother upgraded his printer which uses a 3mm filament instead of 1.75mm. This was amongst that. Lucky me!  :D  ;D

So, first up, I used the dark grey that was already on the printer (close enough in terms of colour, and it prints beautifully) and got the base of the rotor down...

I actually had to print it twice; the first time, the first inner ring wasn't quite large enough to accommodate the rotor housing tube. After the second print, the exterior was slightly too large to fit nicely into the rotor gap on the console, but that was a hell of a lot easier to deal with (ie an electric vibration sander), than the inner ring would have been...



I hadn't used the clear grey before, so I was uncertain as to how it would print. As it turns out, very well...


The interior detail of the rotor was designed in a way to give the interior some rotational movement, with the separate layers moving in counterpoint to each other. I haven't quite figured out yet HOW I'm going to get them to do that, but since this is still essentially the prototype I figure I've got some time to work it out. Was also designed in such a way that it could be printed effectively with no overhangs, be centralised without slipping and sliding, and to give some inner life and texture to the rotor, without being overly complex that it was impossible to print. I think I found a happy solution (mostly)...


... there are 4 larger "stars" to make up the rotor. The 5th "star" on top is solid, but has a hollow tube that runs down the centre of the lower 4. It means the whole thing is essentially closed off, but is hollow so that the interior of the rotor can be lit, and give off that nice glow that appears in my renders...



The remainder printed without any issues...

... which only leaves assembly...





... very happy with the result. I'm just thinking I may also go ahead and print the small triangular pieces that are recessed in the edge of the console. I have the clear already on the printer, so why not? Also... I'm getting bored again!  :P  ::)

I'm guessing I'll be talking to y'all again in the next day or so.

In the meantime, a nice gratuitous shot to send off the post...

Tiny, small, eeny-weeny update:

1) Attempted to print the clear, mid-console inserts (the tessellating rhomboids that go around the perimeter of the mid-section). Not particularly successful, they just may be a bit too small for that. I am considering other options. Was thinking about blobs of hot-glue, pushed in and then scraped off at the edge and allowed to set. The only trouble is, you don't get a great deal of time to get it right, and if you get it wrong, then the console could be ruined. But I like the idea of some kind of malleable, clear plastic that can be pushed into the openings and allowed to harden. Does anyone have any good ideas?   :D  ;D

2) Getting bored and antsy again, so I thought I might attempt to print a wall section or two. Turns out, there is a fairly major design flaw with my larger wall sections, ie they're too large to fit on the print bed!  :o  ???  ???  I don't know how I missed that! That's a BIG f***-up! Normally I'm pretty good with details like that, and I thought I had accounted for the piece sizes correctly when I did the sub-divisions. I'd even confidently made material quantity calculations based on what I had produced. Just as well I hadn't made any purchases at this point. As mentioned previously, the metal-fill PLA is expensive. It's important to get this right. And it's more than just the sub-division of the parts. I can't simply go through and re-sub-divide; a quick check shows that smaller sub-divisions won't work, practically or aesthetically. I need to go through and re-model the walls, making a smaller (although hopefully not noticeably smaller) console room. It's fortunately not going to be too difficult or complicated to do. Solidworks gives you a lot of freedom with regard to changing major design elements that were used early on to base the rest of the structure off, and then rebuild around it. It's a pain in the proverbial though. Just as well things have been proceeding in the way that they have thus far, or I may have caught it too late. Just as well the f***-up fairy was doing the rounds and decided to visit this week!  ::)  :P

Sorry for those who may have been hoping for a more positive and progress-filled update. I'll do my best to remedy that as soon as I can.
