About this 3D model
Recently, I had been building a modern footbridge with Lifts, and as I was building a version for my Model Club, I thought it would be nice to put the British Rail Double Arrow on the side of the lift shaft building. So I did a bit of research and found the design online and how to draw it correctly. With the measurement I had and the size I roughly needed came out as 32mm wide, 20mm tall, and I made it 0.8mm deep, which is 10 layers of 0.08mm with a 0.4mm nozzle. If you need this Double arrow bigger or smaller, then it can easily be scaled up or down without affecting its ability to print. When I printed the first one on my Bambu Labs A1 and then stuck it on the side of the lift tower, I knew this was quite a simple design, but I had the thought someone else might want to use it, and that's why I have shared it for others to use. I used ELEGOO PLA+ Red Filament - https://amzn.to/3KUH8Tf (affiliate link) designed at OO gauge, 1/76.2 scale but can easily be scaled for other gauges.for HO gauge print at 87%, 1/87 Scale,for TT120 gauge print at 63.5% 1/120 Scale,for O gauge UK at 175%, 1/43.5 Scale,for O gauge International print at 158%, 1/48 Scale,for N gauge print at 51.49%, 1/148 Scale, (Caution: I have not printed this model in N gauge, so I can’t guarantee its printability) The example in the pictures was printed on a Bambu Labs A1 FDM Printer.
