Customizable Dowel Rod Shelf

thingiverse

An easy, non-invasive light-weight shelf to put inside a window frame. The uploaded STLs can be used with four 3/8in dowel rods, which cost me just $6.05, making it the cheapest shelf I've ever installed. I'm still working on perfecting the thread settings to find the ideal balance between print-ability and strength. After some trial and error, I finally found a setting that works well: printing the threaded rod piece at 100% infill is crucial. This ensures that the piece can withstand being driven into the end cap with pliers without breaking. This customizer takes a while to compile, especially if you increase the resolution. The uploaded STLs were created with a resolution of 50, which I find superior to 24, but it does slow down compilation. To give users more flexibility, I've included a zip file containing individual OpenSCAD files for each piece. Print Settings: * Printer Brand: MakerBot * Printer: MakerBot Replicator (5th Generation) * Rafts: Yes * Supports: No * Resolution: I recommend using layer heights between 0.1 and 0.2. * Infill: The DynamicCap and DynamicExtension require a high infill percentage (30-40%). Notes: Smaller layer heights will result in a smoother turning screw. If you're experiencing issues with the threaded rod fitting into the end cap, try increasing the "extra_space" value in the customizer or using a layer height less than 0.2. I designed this shelf to be printable on my MakerBot Replicator (5th Generation), and I'm pleased to say it's worked out well. I've also created a version for my MakerBot Rep 2, printed at a 0.1 layer height, and they turned out beautifully.
