There aren't many 1/3 scale BJD sofas for sell on Etsy, so I thought I would make an easy printable one.
Dimensions are based on Ikea BALKARP sleeper sofa.
The cushion is just a piece of 3.5cm memory foam cut to 57cm x 30cm with some fabric glued to it "no sewing required." Mod Podge works best for gluing fabric.
The cushion is held in place by a long zip tie which also creates the crease in the middle.
All the pegs are loose. You can glue them if you choose, but it isn't really necessary as the cushion holds everything together by compression.
This was printed on a CR-10s which has a fairly large build volume. I apologize that it won't be printable on smaller printers without some modification.
If you do print this, please post a make. I would love to see it.
