I've seen it suggested to use a 35mm film canister as a source for a collimation cap. However, they're not a perfect fit in the eyepiece. Just for info, you can get Herron brand paracetamol tablets from the supermarket that come in a white plastic bottle with a green lid. The bottle is a *perfect* fit into a 1.25" eyepiece holder.
