The channel letter will be assembled from multiple construction parts. The size of the spaces between them depends on if the assembly should be fixed or loose. It also depends on the manufacturing precision. Especially in FFF 3d printing technology, the accuracy can differ in a significant range. Therefore it is beneficial to have the size of the gaps under control. Glyph Channelier gives possibility to set the size of these gaps.
The horizontal gap defines the distance between two horizontal planes. Similarly, the vertical gap defines the distance between two vertical planes.
It is possible to define the gaps around the GLASS and around the BOTTOM.
