The better air flows through a thermoforming tool, the higher the final part quality. By adding air holes to a tool, you can create parts or molds with higher degrees of detail and prevent air bubbles.
By adding air holes, the air gets sucked into the cavity. Without the air holes, there will be nowhere for the air to escape which will result in poorly formed mold. Make sure the holes are small enough so they don’t affect the mold, tiny 0.5mm air holes or as small as you can.

How to check if your air holes are clear
Because the Mayku Multiplier has a dome-shaped chamber, you’ll need to take the height and dimensions of your tool into consideration, especially if you are forming a large tool, or multiple tools. The maximum forming volume is 3.5 liters. The widest safe forming area is 380mm wide, and 160mm high. It's important to factor this in when designing your tool for thermoforming.
Tall and narrow templates, up to 160mm, can be placed in the centre of the forming bed:
