Overview

For our first group project, we are working on creating an electronic shelf, below are the initial schematics

This block is a proposed design for part “E” in the image above. It is crafted to hold spools and easily move it across the bench without much mess.

Initial Sketches

Sketch 1: this design was to be 3d printed as a single part, but then we would not be able to get the spool in!

Sketch 2: this press fit junction –after some thought- would not be as efficient in such small dimensions.

Sketch 3: the square design would loosen up quickly and turn useless probably after a few weeks.

Sketch 4: the final design is a screw and nut design to solve all the above-mentioned problems.

To create that screw-nut design, you can refer to this short tutorial. The dimensions used here are:

Make sure that everything is fine then find something to do for a few hours until it is done printing””

Once the machine has cooled down, you can bring clippers and start removing supports and rafts.

On a second thought, I think these modifications will extend the shelf life "literally" and make it more efficient. They still need testing though:)

You can find all the source/design files right here. Enjoy your time:)
