THIS 3D MODEL PACKAGE

Name:      B2 Chopstick Buddies - two-piece M26 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 B2 Chopstick Buddies". This is a two-piece flavor of Chopstick Buddies. There is a "model B1 Chopstick Buddies - single-piece M23 PLA" package for the single-piece flavor.

This package includes 2 cap sizes: wide and narrow. It includes 4 sleeve sizes: small, regular, regular, large, extra large, and huge. 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, and a good cap-to-sleeve fit.

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.
