This is a "morale patch" to identify a pack/pouch as a a medical kit. I designed it for use on my Trauma and IFAK (Individual First Aid Kit). I will upload a printable MOLLE clip (https://www.thingiverse.com/thing:2874485) that can be attached to the patch with Epoxy, or use sticky-back velcro.
This patch is designed to be printed in two steps, in two contrasting colors. The standard would be a red base with a white field (as shown in the sample picture). After printing, the field simply clicks in to place on the base. You may need to secure with epoxy, or perform some light trimming, depending on printer accuracy.
A raft is highly recommended, especially for the field, as it is thin an could warp at the edges.
