Originally created by user jmjheaton on XYZ Printing, I fixed the headboard in Meshmixer and remodeled the bed frame in Tinkercad. Uses a common Brillo sponge which you can probably find at your local grocery store. The bed model in the photo came out a bit too large for the sponge, I will scale the next one to about 90%.
Thanks to reddit user throwaway_draw for the sketch!
Print the headboard standing up with a wide brim for better bed adhesion. Print the pillows with the flat face down and the pillows sticking up, no supports needed. Whittle some short pieces of bamboo skewers, dowels or finishing nails to attach the headboard to the frame. Use some dabs of glue to hold everything together.
