HO Scale Rusticated Brick House

HO scale model of a 1920's- to 1940's-era house, featuring rusticated concrete block walls.

Rusticated concrete block is concrete block with a decorative outside face cast to resemble rough or worked stone. This style of block appeared in the late 19th century and was used for homes, utility buildings, and commercial buildings. This model is inspired by a home on Sherwood Road in Mount Hope, West Virginia. Wander the street on Google Maps Street View and you'll find it!

Parts are separated for easy painting or for printing in different colours. The roof is intended to be finished with your favorite roof texture, such as printed paper shingles.

How to determine which walls to use

Which walls you use depends on whether or not you can get the crawlspace vents to print.

vent_frame.stl can be hard to print. Try printing vent_frame.stl first to see if you can make it work.

Print the vent frame at 0.1mm layers with a 0.2mm extruder on a 3-layer raft; the raft material will become the vent mesh in the finished part. After printing, trim away excess raft material from the frame, leaving the fine mesh inside the frame. This trick works very well for for me using PrusaSlicer 2.8.1 and an Ender 3 Pro; I am curious to know if it works with different slicers and printers.

If these work for you, use walls.stl for your model. If the vents don't work for you, use walls_no_vents.stl.

Parts needing supports

• walls.stl, or walls_no_vents.stl, with manually-applied supports on the underside of the door, window, and vent openings only.

• roof.stl will print without supports (the one shown in my sample printed without supports), but you might get a smoother exterior finish with default support settings.

Print at 0.1mm layers with 0.2mm extruder

Print 1 of each unless otherwise noted:

• chimney.stl
• chimney_flashing.stl
• door_sill.stl - print 2
• front_porch_beam.stl
• front_porch_sill_left.stl
• front_porch_sill_right.stl
• front_porch_post.stl - print 6
• front_porch_post_cap.stl - print 6
• porch_post_jig.stl
• vent_frame.stl - print 6, see notes above for info on using the raft as the vent mesh
• window_double_short.stl
• window_double_sill.stl - print 3
• window_double_tall.stl - print 2
• window_single_short.stl
• window_single_sill.stl - print 6
• window_single_tall.stl - print 5

Print these parts if you want the doors and door frames as one part:

• door_back_single_part.stl
• door_front_single_part.stl

Print these parts if you want the doors and door frames as two parts for painting or to print in separate colours:

• door_frame.stl - print 2
• door_back_door.stl
• door_front_door.stl

Print at 0.1mm layers with 0.4mm extruder

Print 1 of each:

• fascia.stl
• front_porch.stl
• roof_locator.stl
• soffit.stl

Print at 0.2mm layers with 0.4mm extruder

Print 1 of each:

• walls.stl or walls_no_vents.stl, depending on whether or not you want to include the crawlspace vents
• roof.stl
