Tacx Flux - Axle End caps

Hi! My colleague lent me a Tacx Flux, with a type 1 axle. He had a bike with disc brakes so he used other end caps / adapters to fit his bike on the flux. He lost the orginal quick release end caps. So i am looking for: the QR 130 DS - Type 1 adapter (which comes with the flux). My local bike shop can only provide me with the type 2 end caps… on the internet i cannot find the older type 1 caps. Has anyone an idea where to buy them? 

They look like this, but these fit on the type 2 axle..

Thanks in advance!
