Any suggestions for a do-it-yourself method to boost security?

I own a CB6000 and have experimented with various spacers and ring sizes, yet I can still pull it out. There is the KSD-G3 on sale which supposedly prevents or reduces this issue, but my budget is tight right now so buying another one isn’t an option for me. Besides, I want to avoid any piercings. Long ago, I recall reading about someone inserting something into the tube to create drag or fill space when pulling out. I don’t remember exactly what material was used or how it was assembled, but they got it cheaply from a major home improvement store and found it very secure. While I know ultimate security is mostly mental and requires self-control, I’d love that sense of helplessness—knowing for sure I can’t escape without being caught.

Does anyone here have suggestions or ideas?

Here is one design I created myself... Actually, I made two and gave one to a friend who also owns a CB6000. We both ended up purchasing the JailBird from MatureMetals since these homemade ones seem inescapable. I used 6mm thick polycarbonate sheeting to create three prongs (similar to the "Points of Intrigue" available for the CB3000). Because there are construction differences between the CB3000 and CB6000, you can't interchange the official points between these two devices. If I locate the CAD file, I will upload it; however, making one is quite straightforward. Use the flat surface of the cage as a guide to mark where the pins pass through, sketch the general outline, then draw a concave semicircle that protrudes inward toward where the penis shaft would sit. Carve teeth into this semicircle so the points press against the shaft. Drilling the holes requires care, especially the central locking pin hole because there isn't much plastic around them—you could drill first and then cut the outline. For assembly, use the "points" plate as one of your spacers. Trust me, even if the points are somewhat blunt, you won't want to try pulling past them. Getting an erection while wearing it is risky—don't say I didn’t warn you:shock: They would work well for tease-and-denial scenarios if a partner helps play with you:D
