The prototype was 300 feet long, which would be 41 inches (1051mm) in HO scale, so I've selected key elements from the shed and created a model where the parts will fit on a 220mm × 220mm print bed.
Parts are separated for easy painting or for printing in separate colours.
The kit includes two sets of wall parts. Use the "top" and "bottom" parts to print the walls in separate colours to get the two-tone colour scheme common to railway buildings. If you want to print the walls as single parts, use the "one-piece" parts.
The kit includes two foundation parts. My brick foundation is not found on the prototype, but I just really like brick foundations. Use the "plain" foundation to better represent the simple board skirt that was likely found on the prototype.
The roof is intended to be finished with your preferred paper-printed roofing material, such as shingles or tar paper.

Assembly
- Print the parts and remove the support material from the chimney flashing.
- Assemble the wall tops and bottoms.
- Fit the wall, door, and window trim to the walls.
- Assemble the walls, using a small square to align the corners.
- Fit the doors and windows.
- Glaze the windows with your preferred glazing material.
- Fit the assembled walls onto the foundation.
- Fit the soffit into the recesses on the roof halves.
- Fit the roof halves to the walls.
- Fit the chimney into the chimney flashing and glue the chimney to the roof.
- Assemble the long loading dock frames. Glue one dock_frame_back_face.stl and one dock_frame_front_face.stl back-to-back. Repeat for the second loading dock frame.
- Assemble the loading dock cross-braces. Glue two dock_crossbrace.stl parts back to back. Repeat to create 8 cross-braces.
- Assemble the loading dock frame. Fit the assembled cross-braces into the locating recesses on the back of one of the assembled long frames, then fit the second long frame to the cross-braces.
- Fit the loading dock planks to the assembled loading dock frame. The front of the dock planks has small gaps between the planks. Position the planks so that the back of the planks is flush with the back of the frame and the planks are centered left-to-right on the frame.
- Fit the assembled loading dock to right side of the structure.
- Fit the truck_bumper.stl to the recess on the left wall.
- Assemble the steps and porches. Butt one stairs_front_frame.stl to the back of one stairs_side_frame.stl and glue. Butt one stairs_rear_frame.stl to the back of the same side frame and glue. Butt the back of a second side frame to the front and rear frames and glue. Glue one stairs_porch_planks.stl to the assembled frame, making the back of the planks flush with the back of the frame. Repeat this step to assemble the second frame.
- Examine the stairs_assembly_jig.stl. The pointed side of the jig is the "bottom" of the jig. Examine the stairs_stringer.stl parts. Note that the last riser on the stringer is shallower than the others. The shallow riser is the "bottom" of the stringer. Place three stairs_stringer.stl parts into the slots on the stairs_assembly_jig.stl, aligning the bottom of each stringer with the bottom of the jig. Nudge the stringers so they fit evenly in the slots.
- Now, seriously - this is a lot more fun than it sounds! Be careful to avoid gluing the stringers or the steps to the jig. Apply glue to the underside of one stairs_step_planks.stl part, and drop the part onto the first notch on the stringer. Use the raised ledge of the jig as a stop to position the planks on the stringers. Press the steps into place to ensure the step glues to each stringer. Repeat the process to assemble five steps in total on the stringers. Repeaat this entire process to assemble the second set of steps.
- Fit the assembled steps to the assembled porch frames and glue.
- Fit the assembled steps and porches to the building.
