Ultimaker 2 and 2+ front window clip

If you're using ABS, make sure to seal out external air currents. To ensure a solid bond between the ABS and surface, mix pure acetone with a piece of natural ABS filament in an airtight container for a full day before applying a thin layer of film to the cool surface. Wait patiently as it dries completely. My front window measures 28cm wide by 34cm tall and just 3mm thick. The clips designed for this precise dimension leave no room for error, so if you can't get them to fit, try using sandpaper - I recommend a 50% fill coat. Good luck with the process.
