Thanks teamhalo, I decided to do batteries in different types as my first project because they're fairly simple shapes, and I could only find one battery (apart from various types of car battery) in the store, and what with smallg giving away his flashlight battery script I thought it would be a great opportunity for me to give back to the community, you're welcome to use the batteries for whatever project you like commercial or not
I need to redo the texture on the pipe though, I noticed when putting a couple end to end last night that the texture isn't quite seamless, it a little darker at one end so los odd when you lay them together, all I need to do is flip a copy horizontally, stitch them together and scale them down, it only needs to be seamless horizontally, the vertical seams are behind the model and not visible.
The pipe is eventually going to be a pack of pipes that link together, it will include t-junctions, elbow bends, and both horizontal and vertical pipes in a couple of lengths, as well as (if I can do it) a couple of animated drips and some puddle decals.
I've decided to do the animated drips separately to the pipes themselves, i'll probably make them to drop from a couple of meters above head height, that way they can be moved up or down and the drips won't disappear before hitting the floor if you move it too high.
