The latest in my Doctor Who/Transformers crossover toys!

The main artistic reference for the Dalek mode was the 2005 season episode 'Dalek', and the amazing WETA sculpture of the Dalek with the shell opened up to show off the interior. The transformation geometry is original. I took a little inspiration from the transformer 'Octus', who apparently turns into a Dalek in his alt-mode though that was never shown in the one comic he appeared in. Octus mostly inspired this design to have multiple arms. I also took inspiration from the half-human hybrid Dalek Sec from the episode 'Daleks in Manhatten', in having the Kaled Mutant form the head of the model when in robot mode.

The basic design was done in AutoCAD 2006. I did redraw the mutant in ZBrush to give it a more blended, organic look.

This is a much more challenging toy to print and assemble than either of the Tardis transformers I posted. There are about 100 parts to be printed, several of which have to be glued together. There are two parts that have to be printed with full support added by your slicer software, and five parts which have small pieces of support already added to the STL files that you will have to cut away after printing.

No painting is required, provided you stick to the filament color recommendations.

The original shown here was printed in PLA on my scratch-built Delta style printer. It takes a total of about 10oz of plastic, mostly gold and black with some silver, grey, and purple. Total print time on my machine is about 32 hours. The toy stands about 6 inches tall in Dalek mode, about 13 inches tall in robot mode. All of the parts are individually small so you should be able to print this on any size printer.

Update on 10/13: Changed upperbody_inside left and right to add a small stop to help prevent the dome from rotating forwards when in Dalek mode with the front of the body open.


This is a MUCH more challenging piece to build than my Tardis Transformer. There are about 100 parts that need to be printed. 2 of them require full support to be turned on when you slice them. 5 more have small pieces of support I've added in that you will need to cut away after printing. Many of the parts need to be glued together during assembly, and there is one joint which needs a small piece of 1.75mm filament inserted as a hinge. There is a good chance you will break parts of this while assembling it unless you follow the instructions very carefully.

I have included an assembly document with many photos showing how to build this. It's still a challenging build even with that.

It's also fairly tricky to transform, with many small fiddly bits that are hard to get into exactly the right places. I am working on putting together a transformation guide.

love this model!!! assembling now one thing i really want is for the legs and arms to have indention and the little domes be glued in so that it would look super real with contrasting colors. up for it?

I'm working (slowly) on a revamp of the entire design. I'll look at making an option to have the domes separate snap-in pieces so they can be colored differently when I do.

Hey, is there any way I could get one made? I would love to have one for my mom, shes a HUGE fan of doctor who and transformers, I dont have enough money a 3d printer though. Thanks for reading.

wow that would be amazing... well i look forward to printing that very much and ill post pics of this build as well... i love both the dr who tranformers you made they are the top 2 favorite prints ever!keep it up

Ok, I've printed out about half the pieces and I'm onto assembling the legs. Um, the cyanoacrylate doesn't even pretend to glue PLA together. So I'm now waiting on another round of glue (acrylic adhesive) before I can continue. Other than that, I'm in love with this project.

I wondered what was inside of a Dalek!

can you put the pieces in plates, I dont want to download all the pieces

hit the download all button and just unzip it

I still love it

This is unbelievably cool. I don't have a printer yet but I'm going to have to try making this when i learn how to use what I've got coming.


This thing bleeds awesome!

tips hat
magnificent work! :)

Thanks! I used your Dalek model as a base, although I redrew every part of it from basic geometric primitives in the process of making my design.

So goooooood!

I'm sitting here shaking my head at the thought of how much time it must take to dial in these transformer designs. Thanks for the hard work :)

Yep. About a month of weekends and evenings, including one entire week I had off work (involuntarily due to furloughs) during which I did almost nothing other than design this thing. And I think I threw out enough failed parts to make at least two more of these before getting the design just right.

That is an impressively low failure rate! I go through way more iterations on my designs and they aren't nearly as complicated. My hat is off to you sir.

"Dalek Mutant" is actually called a Kaled I believe.

Yeah, I know. Didn't bother to label it that for this as I was most of the way through the design before I realized that, and didn't bother to go back and change the names of the files.

Saw the writeup on this the other day. You have done an amazing job. Thank you so much for releasing this into the wild.

Thanks! It's a challenging piece to print and assemble, so I'm actually a bit worried about how well and if anyone's even going to be able to make their own. I tied to spell out all the difficult bits in the assembly diagram, but it's still going to be a challenging model to assemble.


Holy Mackerel! This is freaking awesome! Warming up my printer right now!

The longest dimension I can find on any one piece is about 100mm, so you should be able to print everything on a machine with a 120mm bed. There are just a lot of pieces to print, and a few of them need support.

Thanks for checking that out! It is much appreciated for those of us with smaller bots. Are you planning a simpler version like you did for the Tardis?

Not sure yet. Part of the reason I made a simpler version of the Tardis was because the first one was mechanically terrible, easy to break, incapable of standing unsupported, and not holding together well in Tardis mode. This Dalek is large and complicated, but mechanically it came out very nicely. It stands unsupported very well, the joints are tight enough for it to hold a pose, and it holds together very well in Dalek mode. Even though it's large and complicated to make, I'm really happy with the mechanical design. I might revisit it at some point in the future to make a simpler, smaller version, but I have a few other design projects I have to tackle first.
