Printing Instructions: https://marcosticks.org/model-h-finger-helpers/

Always go to the above web page for actual printing instructions for this particular model. But here is a quick rule of thumb that in general works for most Marcosticks 3D models:

* The 3MF files are PrusaSlicer projects, with our own start-up GCode for MKS3.
* The STL files can be used direct in your own preferred slicer.
* Print in PLA - it's stiff enough for marcosticks parts.
* Finger helpers can be printed at anywhere from 20% infill to 100% infill.
* 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.

Enable "Detect thin walls" in PrusaSlicer, or the equivalent in your slicer. Without this setting, PrusaSlicer will always use 2 perimeters (one outside and one inside), for all walls. The finger helper has a thin wall. If you slice it to print 2 perimeters, the sleeve will become too thick. Turning this on instructs the slicer to produce only one perimeter for the thin walls in this model.

Post-Printing

The ends of a printed sleeve will be ragged. Such ragged edges on the inside wall of the sleeve will cause the sleeve not slide all the way into a marcostick, to its intended target location. Use a deburring tool to clean inside edges of both ends of the sleeve.

Optional Mark-and-Go License

We made 3D models available on MyMiniFactory with a strict, CC non-commercial no-derivatives license. You can choose to follow this strict license for personal uses.

But we actually made a much more lenient license available, if you want to create derivative works, or commercialize these training marcosticks. Please consult the Mark-and-Go Marcosticks license. Here is a quick summary:

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.

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.
