Description

This is a parameterizable ring made in OpenSCAD with a “BHat” logo for the Baltimore Hack-A-Thon.

It was created as part of the Nickel for Scale project, which you can learn more about at http://nickelforscale.com/

Instructions

You’ll need both real_bhat_ring.scad and B.dxf to render a custom-sized ring.

To resize the ring without Nickel for Scale:

1. Edit the inner_diam in OpenSCAD to match the diameter of your finger.
2. Render to STL with OpenSCAD.
3. Print!

To resize the ring with Nickel for Scale:

1. Get Nickel for Scale from GitHub: http://github.com/martymcguire/NickelForScale
2. Install Processing and all required libraries.
3. Set up your webcam and configure the NickelForScale sketch with the right capture info.
4. Run NickelForScale, choose the BHat ring (it’s built in), follow the instructions, and generate the ring.
5. Your custom ring will be in the NickelForScale/data/ folder.

To change the letter:

I used Inkscape to generate the B. To use it with OpenSCAD, I saved a copy as Encapsulated Postscript (.eps), and chose the option to convert the text to a path. I then used pstoedit to convert the .eps to a .dxf, which is the format that OpenSCAD expects.

Description

Time to get organized!

For years I’ve had a pair of metal interlocking file stands in a set of wood drawers for holding files. For almost as many years, the plastic brackets that secure them in place have been broken and useless, letting files flop around at will.

Today, my partner offered a trade: if I fixed the file cabinet, she would do all of the house cleaning. Needless to say: OFFER ACCEPTED. :)

You can tell from the pictures that I’ve got a long way to go as far as quality settings with the PLA 4043D and MK5. The MK5 puts out plastic FAST and the PLA stays hot for quite a while, allowing it to sag. I’m sure I could improve this with some cool settings, a faster feedrate, lower temp, maybe a fan blowing on the work piece, etc. Instead, I padded out the values for the holes and hollow areas with some multipliers in the .scad file and everything works great!

Instructions

1. Measure out the clip that you’re replacing.
2. Update the .scad file (be sure to curse me for the sloppy code) and export STL.
3. Use Pleasant3D or ReplicatorG to center the object in the STL.
4. Slice.
5. Print (x 2).
6. Screw into place.
7. File!
