Mini-R2

Mini update!

My original plan was to do a 40% scale version of my R2.

Well .. This plan has changed. The new plan is to make a 50% scale version of R2-D2.

Why the new format, you may ask? –Well, the slightly larger scale makes the details really pop out from the printer.

I can’t print the entire dome in one go, but I might as well split it in several parts. The first proper dome print was splitting the dome in half, and printing it in halves. It came out really well.

It is quite thin at this point, but once ready, the parts really look good.

It also means I need to print a complete new set of greeblies for the dome, and of course, the old 40% leg struts and parts done, needs to be remade as well.

I just think this is so cute.. 😉

The second dome I made much thicker, and split in 4 parts. The main dome is in thirds, but I also cut off the top to print as one single part as well.

Much sturdier…

However, still fragile..

Fortunately, this is an easy fix, and once I have acetone coated the insides, it should be sturdy and have no issues at all.

Mini progress

So, I’ve been bitten by a nasty stomach bug the past week. No fever or anything, just that I’ve been unable to really do anything physical or leave the apartment.

That did, however, allow me to do a lot more on the mini R2. Got lots of things designed and redone in my CAD program, but the printing is lacking behind, as I am starting to run out of filament and also waiting for an upgrade kit for my printer 😉

Anyway, I have done a few prototypes of the dome. Printed one of them to try out a few things, designed a new version after the first one, but still waiting to print it.

I have printed a few other bits and pieces in the mean time.

Have a look.

All pieces are drawn by me in Rhino for Mac. Design for 3D printing of these parts also by me.

And no. I will not make any parts to sell to you.

First off, here’s the dome while printing (really maxing out the print plate, but that was sort of the reason for me going 40% scale). I’ve made a small bearing in PLA that uses 1.75mm filament for an axel. This spins really well.
