3D model of prettysmallthings. The models were repaired and checked for printability.
This is a miniature Queen Anne style chair, designed for use in scale models...Show more and dollhouses. The files below are provided in 1/2" = 1'-0" scale, also known as 1:24.
My design goals were:
Maintain delicate proportions, but balance the need for durability.
Print without support
Good looking resolution, with little cleanup needed
This does print at 50% (1/4" scale or 1:48) but is very fragile. I imagine that printing at 200% (1" scale or 1:12, typical dollhouse scale) would require support, and I have not tested it.
I printed this on my Thing-o-matic MK7 with a (well leveled) HBP, using the standard 0026 profile, with print-o-matic set to 30mm/sec federate, 20% infill and a layer height of .3 and no support. I've been printing them in sets of two, as it seems to take about the same amount of time to print one as it does two. I printed with an extra large raft, increasing the raft margin to 10mm.
The "double" file contains small discs underneath the chair legs which help the legs survive a knock or two from the extruder, which seems inevitable in my setup. I've provided a single chair, without the discs, for the better tuned and more adventurous users out there.
I use a hot knife attachment on my soldering iron to clean up any loops or nubs, and separate the legs from the discs & raft.
If you have recommendations for achieving better print quality, I'm all ears!
