Step 1: Collect Your Materials!
- material your making your bag holder with, such as wood, acrylic, etc
- laser cutter
- some adhesive to hold the layers together and make sure your adhesive is able to bond the material your making your back scratcher out of
Step 2: Bag Holder Design
Download the STL file for this thing.
Step 3: Downloading Autodesk 123D Make and Importing the STL
Then your going to click on the "import" button to import the STL file that we downloaded earlier.
Step 4: Slice the STL File Into Layers Using Autodesk 123D Make
Step A: Click on the pencil button to find or add the material that your cutting your material out of. You'll want to specify the name of this material for your own reference, and then the height, width, and length. Everything else you can leave alone =)
Step B: Double check that this is the same units as the model, so that you can look at the height, width, length and double check if everything looks right.
Step C: It seems that 123D Make will change your dimensions if it can't accurately represent the object material your cutting with. However, you can select the Original Size radio button to force it to stick with the original size. (In my case, the bag holder was sectioned into three stacked slices, but the two outside slices ended up not being the same thus the bag holder isn't symmetrical. I'll tell you how to fix this in a later step.)
Step D: Select the "Stacked slices" option, which should slice it in the correct orientation. If not use the "Slice Direction" button on the left and drag around the little pointer that appears around the model. The number of slices you'll need depend on the thickness of your material and the direction of the slices.
Step 5: Export the Vector File
Step 6: Alright! Now We Optimize the Vector File
*Remember how I said uniform scale can mess things up. Well here I couldn't tell because the differences were too small to see, but the handles ended up asymmetrical. So for me, I got three slices, but the top and bottom slice weren't the same size. What we can do at this step to fix it, is to select one of the slices, and just copy that multiple times. This way we can at least get a nice flat handle that overall has the dimensions we want.
Step 7: Fire Up Da LASER!
Step 8: Remove and Arrange Slices
So instead of using all three slices together that creates this odd asymmetrical handle, I paired them up since I doubled it up earlier.
Step 10: The Foundary
These bag holders were Forged by the Iron Vices of TechShop. *Voice of Gandalf
