Hero of a Thousand Devices [R2 Build Log]

ConnertheCat · Post by **ConnertheCat** » Tue Feb 17, 2026 6:01 pm

I'm a few years into my R2-D2 Build, figured I'd share some photos/videos. I started in late '23/early '24; then took a long break to some personal stuff. I jumped back in late last year after about 1 year off, and am currently re-printing the center body for a few reasons. I'm hoping to get a lot of progress done this year, especially since I've done a ton of the hard work along with the electronics while I let the physical form languish for a bit. He's 3D Printed, and while some of the plans are out there the electronics are mostly my own creation - in no way would you consider this a "kit build":

The dome, with lights!

Here's his head mounted on (what is now his old] body - with spinning head and sounds:

I've been spending a lot of time condensing all of his electronics down to a board that fits in the body though:

And here he is, in the "3D Printing Lab" I've set up in the house - Don't fret the helmet on the left side of the table there, just another project I'm working on :

He's full size, 1:1 to the one from the movies.

As good a time as any for an "I don't work for no two-bit Nazi" refresher. ❤

Indeed! I have the jetpack in pieces as well; and was sanding down the helmet when it became Hoth-like outside. I hope to get that done later in the spring.

Thanks for all the kind words folks! I hope to have him on his feet this summer and driving around. I'm currently printing out the new body, ideally that will be all set for paint this spring (April?). I have an issue of perfection on him I'm working to get over; most people aren't going to look at small seams from an inch away on something this size yet I still must try to get it perfect.

Long term, I'd love to do an all metal one with all the bells and whistles; and now that I've sort of set that in mind getting this one out the door can tide me over and help me perfect the drive/control systems.

I also want to make a Chopper. And a BB8. And a Wall-E.

…

Please send help.

That may or may not have solidified the Wall-E build for me someday lol. It was interesting to hear the control system they are using (Kyber), as that's an R2 system.
