Summary

I used the files from svenyonson and made the holes 9mm in diameter (they were 9.5mm). In the UK 9.5mm is not commonly available at hardware stores, whilst 9mm is. The info below comes from svenyonson:

The bases are as follows:

Support base 1 (3 levels), (base and support integrated).
Support base 2 (base and support still integrated)
Plain base for trestles 3-8
The dowel lengths are as follows. (2) per trestle. For trestles 3-8, there is a mid-level support. All you need to do is to have this mid-level support exactly 88mm below the top support. (distance between either bottoms or tops, not the distance from top of one to bottom of the other). I cut a piece of wood to 88mm as a handy measuring stick.

1 - 197mm
2 - 120mm
3 - 131mm
4 - 142mm
5 - 153mm
6 - 164mm
7 - 175mm
8 - 186mm

You will notice that going from the shortest (2) full circle to the tallest (1), the increment is 11mm. Trestle 1 is the tallest because it has a 3rd level.

Assembly:

Insert (2) curved tracks on the high side of each trestle (angling the track down towards the prior trestle) using the female side of each track. Then drop the prior track assembly (males) into the current track assembly (females) from above. Repeat all the way around.

You will need to print:
(1) Support Base 1 (trestle 1)
(1) Support Base 2 (trestle 2)
(6) Base (trestles 3-8)
(15) Supports (trestle 2 does not need a lower support)
