Elegant Print-in-place Chain Drawer Handle

Designed for the Drawer Handle Contest I wanted to submit something that was stylish looking, and showed off forms that 3D printers can do. As well as a type of idea that hadn't been submitted yet. 

This design features 2 different print-in-place style geometry types: the pre-linked chain that can print without supports, and print-in-place pivots so the ends of the chain always hang at a natural angle without having to get it just right on installation. I intentionally left the poly-count of the models low as when printed in a shiny filament it gives a peened like texture I believe looks great. In the printed example I use a dual extrusion filament of copper-silver 

I have also included a version without the pivots (version 2) if the strength of that joint feels like its going to be an issue in your application. 

Sizing 

One of the benefits of the handle being made from a chain is that the mount to mount distance doesn't need to be very precise, but if you want to add or remove links in the slicer “ungroup” the bodies from each other then you will be able to move, duplicate, or delete links.

The mounting holes are sized for M4 screw to self-tap into the plastic. if you want to use a different size screw, or would like to use brass inserts you can adjust the diameter of the holes in the slicer using the “Hole Horizontal Expansion” tool. 

Print Settings

The shown example was printed with a 0.4mm nozzle

• Line width: 0.4mm
• Layer Height: 0.16mm
• Wall line count: 3
• Bottom layers: 5
• Top Layers: 6
• Infill: 30% Tri-Hexagon
• Cooling: Yes-please

Inspiration

I modeled everything from scratch myself so it is not a re-mix, but I would be lying if I said I wasn't inspired by https://www.printables.com/model/44569-franco-keychain/comments/351182# so I'll acknowledge them here.
