Bending acrylic: simple as that!
Acrylic is supplied with a protective film on both sides. You can leave this foil on while bending, and you can also mark the fold lines on it. Mark off the bottom fold line, the point where your tablet meets the bottom, at 3 centimetres from the bottom edge. The second fold line is 30 centimetres higher, i.e. 33 centimetres from the bottom edge. If you have a larger or smaller tablet, then the distance is correspondingly larger or smaller, that goes without saying.
Now place wooden slats under and above the fold line, making sure that they run exactly parallel to the fold line. Keep the slats in place with a pair of glue clamps. Now, you are going to heat the folding line with the paint burner / hot air gun. Set the temperature to ‘medium’ and set the blower to ‘high’. Hold the hot air gun 10 centimetres from the acrylic and gently move it from left to right over the folding line. Occasionally try to bend the acrylic, if the material is flexible enough, bend it up 90 degrees. Then switch off the hot air gun and hold the bent part for about 1 minute. The acrylic then becomes hard again and the fold is fixed.
Heat and bend the second fold line in the same way, with the main difference being that this fold will be at a much sharper angle. Therefore, heat and bend this folding line first to a right angle. Next, heat the folding line for a second time and bend the tablet stand to the desired angle. Then hold it in this position for two minutes until the acrylic has cooled down. Just remove the protective film and your tablet holder is ready!
