First of all thanks to the uploader who shared his bogota's image with a ruler attached, I simply measured and converted the values to centimetres.

It is interesting to note that SO's pagoda set sports the same value (to be exact the peaks are 0.05 millimetres off), but as the SO pagoda is not so rounded that might be the cause for that.
Here is the pagoda set from Southord:

Kudos to the user (can't remember the name as I downloaded lots of images and lost track) who oploaded Raimundo's bogota set next to a ruler.
Hope this helps any DIYer who tries to make them, instructions are available elsewhere on this site.
