#3DPNSpeakerCover Spirograph Speaker Grill

A spirograph inspired speaker grill (a favorite toy as a child). A slight twist in the pattern as it rises makes it impossible to create any other way. Open and transparent to audio. Prints flat on the bed so it can be printed onto speaker grill fabric. Companion spacer ring lifts the grill to clear the rubber surround on the speaker cone.
