Frame for vehicle backseat armrest

thingiverse

This exercise is primarily designed to test how to produce large or lengthy objects with minimal wrapping at the edges due to shrinkage. To assemble the entire structure, you'll need eight screws, two frames, and four rods printed. However, because the rods (up to 264 mm) and frames (180 mm x 180 mm) are substantial, wrapping of the workpiece during printing is a challenging issue that needs to be overcome. A Sofa Storage Caddy Organiser Armrest purchased from the Internet is required to cover the frame. For the rod and frame, two different files have been generated for each item. If wrapping issues arise during printing with .stl files ending in -01, try printing the .stl files with a -02 ending. The -02 files feature wrapping protective boundaries that increase the temperature surrounding the edges and corners of the workpiece during printing. These boundaries are intended to allow them to wrap due to shrinkage and protect the work piece from wrapping. With this simple design modification, it appears that every type of workpiece wrapping can be minimized, resulting in consistent printing results. The drawbacks of printing with protective boundaries include a slightly longer print time (2-5% longer) and increased material waste (1-2%).
