Futon Roller Small

I have an old futon that had single sided rollers but smaller than all that you can buy online or the ones on Thingverse so I modeled these up in Inventor. I printed in ABS 40% infill .20 layer height

Rear Flange is 23mm 2.5mm thick
Part that goes in the slot on the futon frame is 18mm dia x 13mm
End is counterbored for the head of the cotter pin and the through hole is 7.5mm dia

Hope this helps someone else
