How to build a turntable from scratch

In this tutorial i want to show you how build a simple but practical turntable, so you can start with the 3d scanning of your miniatures.

When I want to build terrain or storage boxes for my tabletop games, I always look for material that is as cheap as possible, easy to work with and dimensionally stable.
That’s why I eventually ended up at Depron, a polystyrene-like material that is used in model aircraft construction. I build almost everything with it. It is lightweight, easy to cut and relatively resilient due to its fine-grained structure.

I will now show you here how I built my 3d scanning setup with it.

This is how it will look in the end.

Step 1: Prepare the parts

Here you see all the parts that are needed. It is all made out of 6mm depron plates. We will go through the parts starting from the bottom.

The base top: I made a 24×24 cm base top, added line to mark the center and painted one half black. This is important because this part will be on your photos later on, and we want everything around the miniature to be dark. The front part of the base will never be seen on your photos, so leave it as it is. I added a little arrow at the front edge, this will help me to turn the actual turntable by the exact amount.

The base: Put the base top on a base of any height, so give it a bit of stability and to be able to place it under your LED lamp. My lamp has a quite bulky stand, so i need a height of 4cm. This will of course differ from your own needs.

The base gives your whole setup a certain stability. When you have your heavy S8 TAG standing on the turntable and rotate it for each photo, the rest should not swing or wobble. For this you should install at least one cross brace at the front.

The center axis: A big name for a simple nail.

The turntable: A simple disk, 20cm in diameter, i recommend to add lines that go through the center at the underside. This will help to center it later on.

I prepared some graphic for the top, with positioning aids, colored reference points for the scanning software and 25 segments at the outer rim, so that you can take your 25 photos conveniently. This thing already went through iterations while i gained experience and worked out what i really needed. I am very satisfied with this version now.

You may have noticed a second disc, i called it Turntable Base, beneath the actual turntable disc. This can be of any size, even any shape. It is there to ensure that the nail, that serves as our center axis, does not stick out.

In this case your miniature that is standing directly on it might wobble, especially with all the turnings we have to perform. The figure has to remain in its position, otherwise the scanning will fail.

Another advantage of this is, that the turntable gets some distance to the base and can be turned much easier.

Step 2: Assemble the base

Glue the base parts together using craft glue or styrofoam glue. Stick the nail through the center of the turntable base and after that through the base part. Be sure to hit the center of the base, your marking lines should help you. It is important that the turntable turns around the center of your whole construction.

If you haven’t done it yet, cut out the turntable template and glue it of the turntable top.

Step 3: Assemble the turntable top

Now it’s time to glue to turntable on top of its base. This will also fix the nail. Again, having marked the center axis helps a lot to align both parts properly and to make sure that the turntable is centered out.

After it is fixed, stick it on top of the base.

Step 4: Start the scanning!

You’re done! Place the whole construction under your lamp, maybe add a black sheet of paper behind it as a backdrop, place your miniature and start scanning. 😀
