Lifeform scanner...

So it just never seizes to amaze me all the beautiful craftmanship that some members of the forum goes through, to make sure the parts of R2D2 is up to par! So even an R2 detail which mostly is visible in only one of the movies, can be reproduced to such a detail! This is the life-form scanner, from The Empire Strikes Back. 






Result:


Wow, its just stunning!

Each part manufactured may only be available in small quantities and for a short amount of time. Since these are not produced for any commercial use, only in limited numbers for re-sale to members of the forum. So mostly you could scout the forum for the next part-run or start building your own and try to follow the screen accuracy.

R2D2 really is a swiss-army-robot when you look at all his devices!

...I guess collecting piece by piece when available, and see which parts you can make for yourself is one way to go at it...

Finally got it!!!

Special order this week: the 300 mm dome. FINALLY!

Inner dome

Includes Seamless Milled Bottom Ring

This Hydro Dome Part Run includes:

• 1 Aluminum laser cut outer dome

• 1 Aluminum laser cut inner dome: Inner dome laser cuts include, Radar eye mounting holes, 5 Pie panels, 4 bottom panels to the right of the front HP, these panels are cut with large side tabs (for those who want them to remain static), 3 HP Holes, 3 Openings for Front and Rear Logics, dome bump holes, 2 Holes for PSIs. The inner dome includes hardware for mounting to the inner ring.

• 1 Aluminum one piece bottom ring: Includes hardware for mounting the inner dome to the ring.
The ring is pre-drilled for the "Rockler" Bearing and includes stainless steel hardware for spacing and mounting to the Rockler bearing.

This Dome Fits all CS:L and CS:R parts and frames. Fits all Styrene, Wood and Aluminum Frames.






So I was waiting for this rather important part, since may when the build started. Since may we have had a break from building R2, since first we got married, and then we found a house and have been in a moving process for the last 1,5 month. But as things were coming together, Darren Muller suddenly annonced that the R2D2 aluminium dome would be available in september. And here I was, almost pressing F5 daily at the granite earth home page, everyday since June...

http://www.graniteearth.com/ProductDetails.asp?ProductCode=ALUMINUM-DOME-SET

for resale only to members on the Astromech forum, not intended for commercial use, the interest was still sky-high. So these babies were available only 25 minutes or so, on tuesday (yesterday). And on monday Darren sold the last couple of units from the previous design and those units (might have been 5 of them) were sold within 5 minutes.

So getting my hands on one of these, is a dream I have had for quite some time now. It is essential to our build! <3 ..nothing can really compare to a real 300 mm aluminium dome and unfortunately it is not a piece you can really manufacture on your own!

The previous design I had made a post about it earlier, also had a bottomplate which in this design unfortunately is gone. This is because it was a piece of scrapmetal left over from manufacturing the earlier design. But I think we can solve it design-wise. The important thing is that we got the DOME!

I can not stress this enough. We are looking forward to starting assembly on this wonderful piece! <3

Fixing the 3d printer...

So we have come to this... had a couple of weeks we were busy with the wedding and all, and after that a piece of plastic got stuck in my FlashForge Finder and after that I was to lazy to fix the machine. But now I finally got around to clear the machine of this PLA plastic that was stuck inside. 

That happens sometime and is not very uncommon...





Fixed it! Here is a tutorial...

Now back to printing! ^^

Star Wars Wedding...

So we had a slight break in our build, since we went to Paris and got married! Slightly Star Wars themed wedding, we finally got the churches blessing over our marriage! <3






We are superhappy and now that it's all said and done we can resume our build of our R2D2 unit!

Assemble the wood frame...

We opted for a wood frame, because it seemed like a solid option. We are building according to CS-R blueprints for R2D2,  (revised). We found another member through the Astromech forum that does a run on wood frames. This is made from Ukrainian Birch Wood, exported to USA, CNC-cut and now exported back to Sweden. I guess thats 0-1 for the Climate, but still we got a great looking frame here. I did ask local companies but they did not seem to interested in minimal order of 1 unit, and they just said that I could possible ask local carpenters. So I did ask a couple of those, but seemed busy at the moment.

I guess this was the shortcut instead of cutting the frame ourselves.

If you ignore the RC plane at the far side of the table, the rest of the pieces are our wood frame! :)


Test assemble... we started watching the youtube video I have linked before, but quickly noted that in the video they are using the CS-L frame instead of this one, so we chose to look at the pictures provided by the seller, and we had no problems putting it together.


Fitted, but not glued together...


And ofc we just had to testfit some of our 3D printed pieces so far... 



We did also make a test using cell-foam for filling up parts of the frame which is not needed for eiter details or hatches. We are guessing that it could give some support for the outer-layer-skin and also may give some extra support to the frame and make for a more solid construct. This kind of cell foam doesn't really add any extra weight to the R2 unit.


That's all for now...

3D printing tools...

We have a lot of sanding to do, so one step is to find ways to sand effectively in all the angels. So this is an example of what to do. Olof Geelnard designed this for our use on the R2D2 unit. This is designed at https://www.tinkercad.com/


And this is the printed result, lower polygon count at the bottom to have a better grip when inserted, and the highest resolution at the top, so that is quite solid and sterdy:




And this is how it works...

Death Star plans...

I guess an R2 unit really should have a copy of this file...   just for screen accuracy!

Help me Obi-Wan Kenobi, you are my only hope...



Something like this, to put on a projector screen from our R2D2 unit perhaps? This is Rob Meyer's re-edited Leia message. He actually captured the scene and then edited it frame-by-frame  in photoshop. A crude way, but effective way. https://www.youtube.com/watch?v=tf-1xeE3zzE

Filler and sanding...

Apart from 3D printing alot of pieces there is also all the work with perfecting every part after printing is done. We chose to do all the prints in high-resolution to make it easier to make a nice finish...




R2D2:s arm from the front, there is suppose to be two of them. These are composed of 3d prints that are made in four seperate parts, then glued together. There is a lot of sanding, filler spray, sanding, then more filler spray, several layers...

so there is four parts on each arm, they are printed two at a time, And there is three pieces of sort of like a box, where the arm is folded inside, which are also printed. These three parts (not shown in picture) also takes around 8 hours each, to print in high resolution, and these arms have about 14-16 hours of printing in them already. And that does not include all the work that goes into perfecting the object afterwards...

This is sort of like half way through the process! A lot more hours to go!

Attaching servos to the holo lenses...

So we were really wondering about an effective sollution for the attachment of servos to the hololenses. Just attaching them directly to the 3D printed hololens-part didn't really sit that well with me.

Today I saw this, as another member at the forum, Mowee has made this great printable frame! And it's available as an .stl file through the Astromech.net forum!




It never stop to amaze me, how wonderful this hobby is with all the engineering details, little projects that the community seem to find nice sollutions to, one piece at the time...
