 You can look out for Oldham Couplers with a 18mm mounting hole distance (often they're advertised for being compatible with a Creality Ender 3) - BUT you'd have to swap out the stock anti-backlash nut and use one of the 'regular' spring loaded anti-backlash nuts with 18mm hole distance as the ones mentioned and shown in the expandable textbox "Changing The Anti-Backlash Nut" above (as the stock nut has 20mm distance between the holes which obviously doesn't match the 18mm of the Oldham Coupler).
