Modular PVC Filament Shelf

These 3-way and 4-way connectors are designed for a modular PVC filament shelf system built with ¾" PVC pipes. While other connector models I tried worked perfectly fine, I wanted a design with a smaller footprint, that used less filament, and took less time to print. The orientation of these connectors on the build plate is unusual, but important! Once assembled, the layer lines will be oblique to the loads placed on the printed parts. This makes them less likely to shear at the layer lines when loaded or inserting the PVC. 0.8mm NozzleI designed these to print with a 0.8mm nozzle, which drastically reduces the print time and uses less filament. However, they don't look as nice. I have included a profile for printing with a 0.4mm nozzle if the looks matter to you. Test PrintConsider printing a single connector first to ensure you don't have problems with the fitment of the PVC available to you. These were designed to snuggly fit ¾" PVC with an external diameter of 1.05
