Light cap for roughly 30mm light heads (Designed around Modlite head) but can be resized to fit larger heads. Based off of One Hundred Concepts "LightCap". You must obtain one ranger band or tape and a 12" section of 1/8" shock cord. Recommend printing at 100% infill w/ PETG. No supports needed, print on face.
EDIT* Added “Light Cap Final” version that sized up 3.5mm holes to 4mm and dropped some material off the tab.
