Makerbot Giveaway Entry #1



Shaker Flashlight:
Test print of Inner Case Housing:
Shaker Light Case designed to print on Makerbot:

This is a great idea with some less than perfect quality Chinese manufacturing!

If memory serves I Paid closed to 10 US dollars for one of these “Shaker lights” plus tax. Buy them on Ebay cheap but you must pay the postage, it still costs. No batteries great, simple to keep around and use when needed.

Mine had a few “issues” the switch didn’t lock in right and then I dropped the light and the case got all screwed up. Generally I like the light and concept it just needs to be “personalized” with RepRap.

These make great personalized gifts. My hope with this project is to personalize the lights for areas of usage. Seems I have a bad habit of picking up the light and putting it in another place then end up looking for it when I need it. So the fix is make one that says “Auto” on it, one for Bedroom, kitchen etc.

Problems with the original design you can purchase: The magnet is locked in with a poor seal on the end. The seal isn’t glued; it kinda just locks in very poorly. I highly recommend A decent bit of tape to lock the seal. If the seal unlocks then the “inner works” moves out of position and the power switch won’t make the correct contact.

The power switch is a very simple mechanism. It pushes the metal contact down, makes contact and you have power. As this project is only to replace the casing we won’t address the issues at this time.

The mirror type mechanism is basically some reflecting foil around the led light. One flat piece of reflection does the job but could be improved on. From what I gathered of the design the idea was to give a little light near the top of the light as well as out of it. Serves no purpose other than look cool.

My first run on this project: covers attempts to make a “clone” very close to the original design. It might have worked, but I put out a test print and asked some questions found that making a copy on a Makerbot would push the machine to its limits. So last minute as my software skills improved, the decision was made to start from scratch again.

Overview: The updated design has two parts

1) Inner Case Housing: is designed to be the printed area to use the “Shaker drop in package”. Contents of a self contained shaker power system, led light, and power switch.

The critical measurement is making the “Shaker drop in” package” fit inside your replication. To make this easy for future versions I made and posted a “test print”

2) Outer Case Package: Contents of the Plastic Lens, Lens Cover, seal and “Outer Case Housing”

In this design we focus on the outer case of the design. We have an “Shaker drop In” package, contents of a self contained shaker power system, led light, and power switch. The inner works fits inside of the outer case and is locked in at the top.

My Hope: This someone buys and stocks ”Shaker drop In” packages. They should be dirt cheap to buy in quantity. Resell them in printer packs of say 6 or 12 units.

This is the perfect demo print for shows. Just print out a bunch of the “Outer Case Housings” maybe personalizes with “made on Makerbot” or some such.

At the demo personalize a name on the Lens cover and make a quick print.

Great as a giveaway and great for giving personalized gifts!
