Control stakes made using electric fence posts and 3D printed tops connecting to a SPORTident control mounting plate were first deployed by WCOC over 12 months ago. Since then, the original design has been improved. I've now manufactured over 90 control stakes incorporating electric fence posts and 3D printed items. Different 3D designs have been produced to mount four different types of SPORTident control mounting plate.
Speculative designs have also been produced to mount the older EMIT EKT controls. These designs, though, are based on estimated dimensions, which may not be correct.
The dimensions that have been estimated are:
Length: ........... 110 mm
Width: .............. 45 mm
Fixing centres: .. 100 mm
Fixings: ................. M4
The EMIT designs are parameterised so can be easily altered as necessary to the accurate dimensions. Therefore, if anyone is interested in these, please contact me so that the dimensions can be confirmed / amended as necessary.
I've also produced other orienteering-related designs for 3D printing. All of my designs are free to use and are available on Thingiverse here:

Related designs from other workers are also available on Thingiverse by searching "orienteering" and "sportident".

Re: 3D printing for control stakes - update
I eventually got round to trying this after reading the original thread.

We couldn't find anyone in our district who was interested in doing the printing for us so we employed a company off the internet, called SGD 3D. They had a lead time of about three weeks and a minimum order price of £30, which is about 10 items depending on size. I don't have the experience to judge the quality of the work, to me it looked rough but OK.
The posts came from fencing-uk in packets of ten. In order to keep the costs down I stripped the old metal poles of their manual clippers and SI station mounting plates for reuse. We had 10 poles for type 8/9 stations and 20 type 7. The type 7 mounting plates were the narrow type which needed an extra hole drilled and countersunk. I used Thing:5436342 for the type 8/9 plates and Thing:5834000 for the type 7 narrow plates as the holes were a bit further apart and I had to drill a new hole through the plates anyway. I ordered a lot of new stainless bolts and nuts from that ebay.
I measured all the poles to 85cm above the top of the spike and cut them with a hacksaw. I became concerned about the amount of glass fiber dust floating about but for some unfathomable reason we had a lot of unused face masks about the house. I drilled an extra 5mm hole through all the printed brackets to accommodate a zip tied manual clipper. The glue I used was J&B Weld, only because I had some in the shed.
The work probably took five hours. The unit cost per pole, buying poles, stainless ironmongery, zipties and printed parts and reusing old mounting plates and clippers came to about £8.
What I can't tell is the durability of the set up.
