A front optics insert style kill-flash making it compatible with any sleeve/slip on style scope cover. I used TPU for print and the default sizing is for front optic found on Vortex Crossfire II 1-4x26.

Example of compatible scope cover: [https://www.printables.com/model/346043-parametric-lens-cap-for-scopes](https://www.printables.com/model/346043-parametric-lens-cap-for-scopes)

Parametric customization available to adjust hex comb size, hex wall thickness, lip width, lip height, and insert wall thickness. Suggest to minimize hex wall and insert wall thickness to reduce light transmission loss.
