Connected Rods: Versatile DIY Solutions for Rod-Based Structures

Note: Any changes will be updated at the end of the description.

This is a project that will expand as I design new components. The core idea is to create detachable structures that can be used as needed: for example, boxes to protect young plants from rodents, plant supports, decorations for annual holidays, mounts for various types of projects, such as connecting components from the Plasticlamp project. Additionally, mini greenhouses can also be made using these structures. I'm opting for fiberglass and carbon fiber rods and tubes due to their strength, affordability, and the convenience of finding them in both metric and imperial sizes across popular platforms like AliExpress and Amazon.

Given the wide range of fiber rods, I plan to design items compatible with both metric and imperial measurements. My preferred method involves printing a tight-fitting version (snug) and then reaming the holes for a smooth connection. However, I will also provide designs for fittings that don't require any secondary operations (loose), catering to those who prefer simplicity.

For simplicity and cost reduction, I will use stainless steel M3 button head screws and hexagonal nuts wherever possible. I envision many structures that I will use and will upload photos over time. For now, I will share photos of the refined and tested 3D printed connectors that perform as well as I intend.

In the initial phase of my project, I plan to focus on designing structures that are primarily based on prismatic and pyramidal forms. These will encompass a variety of base shapes, including triangular, square, pentagonal, and hexagonal configurations. 

I plan to make connectors for straight-sided prisms and pyramids with angles of 75, 60, and 45 degrees.

My initial components were printed using Overture PETG filament, utilizing a standard 0.4mm nozzle at a 0.2mm layer height, following the Prusament PETG printing parameters provided with PrusaSlicer. As of this writing, I am using PrusaSlicer version 2.7.1. When supports are necessary, I opt for Automatic Paint-on Supports with organic structures and 4 perimeters for robustness. These are the basic settings I employ.

You are welcome to suggest new components or improvements regarding the 3D model or the materials used.

Edited 02/03/2024 I've started labeling certain parts with symbols to make sorting easier. These symbols might be updated over time as I discover more effective methods. A Marking Legend is included in one of the snapshots for reference.
