I love the design, it is so cute! I had a hard time assembling it but had tips from NUKDDD so just giving them to you : "You could try run a flow calibration for the filaments you’re using, sometimes they could extrude more than intended. Did you use brim? That could make it not fit if brim isn’t all removed. You could also try to increase the elephant foot setting to make sure the first layer isn’t wider than the rest"
