I've added real vibes to silicone toys that lack them - or that had spots for the useless watch-battery vibes. I've also add more powerful controls to vibes with wires running from the vibe to a controller - it's kinda fun.
I'm already planning on it! My boyfriend and I are going to get an anal plug, drill a hole into the bottom, and attach my plushy tail to it so I can wear it as part of myself. (In case you hadn't guessed, we're into petplay.)
Meh... Probably not. Like If I had my own company yea. Or if me and the bf were doing a clone-a-willy kit or something. But I wouldn't go out of my way to fiddle with parts and make a toy. It probably wouldn't turn out so well haha.
Would you ever make a do-it-yourself toy project to make a toy or modify one? Just for fun?
We drilled some anal plugs to make them "vented" for long term use (must be careful..they easy to damage and cost a lot if made of silicone or steel). We have added new motors or customized plain dildo's to contain both vibrating bullets AND even LED illumination (we love light up toys).
