Acrylic expands with increasing temperature.
Approx. 0.075 mm / m / K, depending on the supplier.
Meaning that a 1 meter acrylic pole will become 1.5 mm longer if the temperature
rises 20 degrees C.
Lacking
knowledge of this is the most frequent error when designing acrylic parts.
The picture to the right show a tolerance that we unfortunately see too often.

In most cases this tolerance is too small for acrylic.
If the temperature raises 10 degrees C, the item becomes 0.15 mm longer
