IKEA (old) KVARTAL gliders

IKEA doesn't sell these anymore and it costs a lot on eBay and Amazon now. So I decided to re-print them using my A8 Anet printer and it comes out exactly what I needed to hang my new curtains. There are two versions - V2 comes with wheels and V3 uses stationary rounded blocks instead of wheels, I found both to be gliding in the rails OK.The bar in V2 can be cut off for pieces as needed.
