Mouse Holster Design Challenge

Mouse Holster Design Challenge

The Goal? To create a storage solution for computer mice that will protect the mouse, the mouse cord, keep them out of the way, and that is durable and easy to use.

Learn from the past:

1. 

Notice how easy it is to hang the cord through the bottom of the brown holster. Compare it to others where people stuff the mouse cord in (tangled and unattractive)!

===================

2. 

The Good? This is thick and durable! The Bad? It's been made too small, too tight, making it difficult to fit the mouse in, much less the cord hanging out of the bottom.
===================

3. 

This one hangs low. It's a lucky thing that it has lasted and not broken. The bottom shows an innovative way to hang the cord, but the user must thread it through every time. Usually, students just stuff it in there, because they are in a hurry to leave.
===================

4. 

Notice how thin the sections are. It's cracked and broken in several places. There also seems to be wasted plastic at the top.
===================

5. 

Compare these two. Both are hard to use at the bottom, but one wasted MUCH more filament, while one focused on saving material.
===================

6. 

This is probably my favorite design up there. Easy to use, durable, smooth, curved edges.
===================

Guidelines for Success:

  • Measure computer mice (with calipers) to figure out how to make your holster SLIGHTLY larger.
  • Figure out how you measure and create your walls, etc. the correct size to start with. 
  • Learn how to chamfer and fillet edges, to save filament. What other strategies can you use to save filament?
  • Plan your pilot holes, like you did for your plaque. We will use screws but you need the correct-size pilot hole.
  • Notice the holster you like using the most. Emulate it, but improve on it! What do you like about it? Think about my comments above!
  • Think about how you have to place your holster on the build plate so that it will print correctly!
  • We won't print massive or teeny holsters that obviously won't work. 
  • I plan to print only the best designs, though all designs can get a grade if you show me when I can type in a grade and talk to you about it.
