We have reviewed and updated the 'Arena' files pack to reflect a revision to the model's layer height options. The files have been optimized to print at layers below .2 (200 microns) e.g. down to 100 microns.
If you have not downloaded the 'Stretch Goal' pack yet, you do not need to update as the pack already includes the update, simply download the main pack, unzip and use.
If you have already downloaded the files before receiving this message, simply download 'Arena-Revised.zip' and substitute the files in that revision pack by extracting over the old files or substituting them manually.
Thanks for reading,
