THIS 3D MODEL PACKAGE

Name:      B1 Chopstick Buddies - single-piece M23 PLA
Video:       https://youtu.be/sbVRqW3Gmwk
Printing Instructions:  https://marcosticks.org/model-b-chopstick-buddies/

Chopstick Buddies are attachments to a plain chopstick. They are designed for beginners, and for a sizable population who cannot hold unaided the thumb pose required by the traditional, standard chopstick grip. 

This package contains parts of "model B1 Chopstick Buddies". This is a single-piece flavor of Chopstick Buddies. There is a "model B2 Chopstick Buddies - two-piece M25 PLA" package for the two-piece flavor.

This package includes buddies in these sizes:
- wide cap + small sleeve
- wide cap + regular sleeve
- wide cap + large sleeve
- wide cap + extra large sleeve
- narrow cap + small sleeve
- narrow cap + regular sleeve
- narrow cap + large sleeve
- narrow cap + extra large sleeve

There is also optional an adjustment strip which you can use as a wedge to fasten a buddie to a chopstick.

Suggested print settings:

Always go to the above web page for actual printing instructions for this particular model.
But here are some key considerations:

* The 3MF files are PrusaSlicer projects, with our own start-up GCode for MKS3.
* The STL files can be used directly in your own preferred slicer.
* Preferred filament is PLA. But all filaments will work for chopstick buddies.
* Chopstick buddies can be printed with just 20% infall. You want them to be lightweight.
* Set layer height to 0.20mm. You can try finer layers if you really wish. But 0.20mm works.
* Enable "Detect bridging parameters" in PrusaSlicer, or the equivalent in your slicer.

Post-print processing:

You may need to use a deburring tool or a file to smooth irregularities in the final print. When everything run perfectly, these post-print processing are not needed. We almost never need to process any chopstick buddies. But if you see minor imperfections, smooth these out to ensure a good sleeve-to-chopstick fit.

LICENSING

Utility patent applications for many training marcosticks have been filed.
A few specific models were also detailed in design patent applications.
But we are making all models FREE for everyone to print on their own,
as long as you follow the Mark-and-go license:

    https://marcosticks.org/license/

You may upload these models to online model repositories,
but only if you clearly label these as Marcosticks, as the license stipulates.
You may make derivative work, but you will need to carry the same 
Marcosticks Mark-and-Go license with the same label requirement. 
You may even reproduce them in bulk, and sell them at profit,
without paying marcosticks.org any royalty fees.
Make sure you follow the Mark-and-go license, 
for commercial deployment which includes quality control checks.

THINGIVERSE AND LICENSING

Thingiverse does not support this type of license.
So we made 3D models available on Thingiverse with a stricter, CC non-commercial no-derivatives license.
You can choose to follow this stricter license for personal uses of course.
But if you want to make derived work, or commercialize them, please consult the Mark-and-go license.

BEFORE YOU USE THESE 3D-PRINTED OBJECTS

Chopstick Buddies do not touch your food nor your mouth, unlike chopsticks to which they are attached to. 
Normally we would warn you about the fact that most 3d-printed objects are not food-safe.
But in the case of Chopstick Buddies, all you need to worry about is keeping them clean, 
and not melting them in a dishwasher.

Regular PLA does not stand up to high heat. 
Don’t put chopstick buddies in a dishwasher – the high-heat sanitizing cycles will melt them.
