Ballast Spacer (Filler) for Freestyler 6 TUD Modelltechnik

This is a simple ballast spacer for the Freestyler 6 (probably 5 as well). The elastic spacer (only one to be printed per wing) has two functions. First to fill the approximately 5mm of space left when the ballast is used, and second to provide a slight pressure to prevent the slugs from moving. The spacer has not been tested. It was designed for someone else. Could anybody printing it, please confirm if the spacer dimensions are good.

To account for all your ballasting options (1 sailplane), you need to print the following number of spacers:

4 x Spacer
2 x Elastic Spacer
