Description

The worst nightmare of ABS printing is warping. These disks almost reduce completely warping.

OK sorry, im reading the instructions now ;)
Hello, need to print with the desing in each work? Or print one disc for various designs?

Thanks
Corrected the filenames and added some useful sizes.

Instructions

Add a disk at each corner of the 3D object you want to print at the bed level. Most of the time, a 1 cm disks does the job. More details are available at ctheroux.com/2013/02/preventing-warping-when-printing-3d-abs-objects/.

The best way to use the anti-warping disk with Slic3r is:

1. Add the anti-warping disks you need on the platter.
2. Add the object you want to print on the platter.
3. Align properly the object you want to print with the anti-warping disks.
4. Save the platter as an STL file. Too much plastic will be extruded if you save the platter as a GCode file right away.
5. Empty the platter.
6. Load the saved STL file.
7. Save the object as a GCode file.
8. Print the GCode file.

This is one technique among others. Brim does not always work well for example with thingiverse.com/thing:35064 . Also, when the object is tick, brims are not strong enough (tick enough) to fight warpage.
You know Slic3r has a feature called 'brim' that works wonders to combat warping. If you don't use slic3r, this openscad file generates one on STL files - thingiverse.com/thing:16728

I find brims to work much nicer than rafts, and the cleanup post-printing is much easier
