It was always a challenge to come up with a way of making proper outside brick corners when scratchbuilding. It always bugged me then I just remembered a few days ago that Tinkercad had a shape generator that I had yet to check out and decided to see if they had a brick wall available. Sure enough, there was one I could play around with. Once I figured out how to interlock them into a corner I thought about a good test. I have both volumes of Jeff Scherb’s PRR plans and it had all of the side elevation views of the long gone Corry PA interlocking tower that served the PRR and Erie’s crossing. I thought it would be a great way to see if the Tinkercad to Elegoo resin printer pipeline was a viable way to make small structures like this.
Here’s what I came up with after some trial and error. Please excuse the quickie paint and weathering job! It is still an experiment. I wasn't sure if I'd be completely happy with everything but at this point the whole project is very promising.
Each side is different. Jeff Scherb's excellent drawings were instrumental in getting everything very close. His drawings even showed the lower Dutch course which I was able to doodle in with Tinkercad.
Here was the first shell attempt in clear green washable resin. This was done straight to the platen and I got a bit of distortion on the bottom corners. At this point I thought I would print this as a shell and then assemble it separately printed windows:
Here is the first shell with a quick shot of primer. The brick shape from the Tinkercad shape generator wasn't perfect but very workable. I may attempt to make my own next time:
The roof was done on my FDM Creality Ender. 3D printing is great for making shapes like this. There were a few points in this project where I had both of my printers going at the same time! I bombed it flat black for demo purposes but it will get proper asphalt shingles at some point.
This is the last successful print where I figured out all my issues and got the shell printed with the windows and door as one unit. This is in black water washable resin. Layer height is .05mm. I printed the foundation on this version and tilted the whole thing off the platen in the X and Z directions.
Fitting up a failed window and door assembly. I wanted to make the windows as thin as possible. I eventually settled for a 1mmX1mm thickness for the final effort. Kinda thick but not overly objectionable.
This was second to the last print. The front window was printed too thinly and fell apart. The resin printer will print whatever garbage .stl you throw at it!
I have these shells in various levels of success/failure. I may try to rescue them at some point. My next tech purchase may be a laser cutter so I can make my own thin parts like industrial windows. That tech, like 3D printing has been dropping in price too!
I'm not sure I even have a use for this building. I just wanted to see if it was going to work. I learned a lot!
