Summary

This mask is for the RASA 11.
Because of printer limitations (300/300mm) you'll need to print the spacerblocks too and glue them on to the mask.
With the spacerblocks in place (also flock the blocks to protect your scope) the mask fits snug between the corrector retaining ring and the dewshieldpins.
Put the starmask on your scope with the blocks facing the correctorplate.
