Size Matters Not - An R2D2 Story

dougw

13 Feb 2019

R2D2 is a monumental icon regardless of its physical size - that has meaning for a large number of people - one of the most popular characters who has no speech.

I have been planning for quite a while to build an R2D2, but every time I took a concrete step towards that goal it seemed to look harder to achieve something reasonable.

This entry is using A Question of Scale as an excuse to move this mini R2D2 project out of the planning stage and into a build phase.

It is great to finally get around to another project from my bucket list. This is definitely a scaled down version of R2D2. I could not find appropriate dimensioned drawings so I tried to take measurements from various images. My painting skills leave a lot to be desired, but that is just another learning curve I need to overcome.

Here is a video of the design, build and demo ....

    Douglas, A detailed design, the CAD work must have taken an extremely long time. I particularly liked the way you have incorporated an existing product (the speaker head) into your design. I might try…

    I was worried about the tiny servo, but it works surprisingly well. Fortunately the head is quite well balanced, and the accuracy of the 3D printer helps a lot. The original DC gearmotor I bought for the…

    A fantastic build. There is an R2D2 builders club, I guess they would have some details (or would be interested to hear about your project)

    Great project. I am really impressed with the fit you get from the 3D printed parts.

     

    I do not know what is available in the US but in the UK we have little pots of enamel / acrylic paints from Humbrol, Revell and Tamiya along with modelling paint brushes of different size and shape. These are popular with plastic model makers but it probably takes as long to do the painting as it does to print the parts off.

     

    Kind regards.
