Plarail to Track master 2 adaptor

Good day All, 
we had a lot of rails from Tomy and new TRackmaster series, but unfortunetly adaptor to conects them to each other a little bit expensive, 5 usd for 1 pc  .  




as you see it was made by 3D printer,
so question is, does some one has a 3d model to print it in 3d printer? 
try to find it in internet but needed not exist. 
thanks a lot in advance.
Regards Yerbol
