Not only is it ALOT easier to get but you know the part is going to work.

Making a mold and filling the mold is just to clone a part you already have. Unless the 'small orange dealie' you have is exactly the same as the one you are missing, making a mold isn't the best option.
You could always travel to homedepot / lowes and browse their aisles looking for some parts that you could improvise with or just get some ideas. Some common materials that are easy to work with for nerf guns are wood, pvc, and thin sheet metal, which are all cheap and sold at most hardware stores.
Hot glue is very strong as a single part when it dries, but it is very hard to release it from the mold you use, because it is a glue... it's supposed to stick to things it touches. I've filled a section of PVC with hotglue in hopes of making a solid hotglue cylinder, but after it dried i couldn't get the hotglue cylinder out of the pvc, it was stuck. So it probably won't work for making a part.

How about PAMing the mold before putting the glue in it?Hot glue is very strong as a single part when it dries, but it is very hard to release it from the mold you use, because it is a glue... it's supposed to stick to things it touches.

Get some clay, putty, or something of that type. Assuming at least one side of the piece is flat, force it into the clay leaving the flat side outwards. *Note at bottom if the piece isn't flat.
Now take the piece of clay (with the object removed) and put it in the oven at about 350 degrees for a few minutes, or until the clay is rock hard. Let it sit for a while, or just douse it in continous freezing water for a minute.
PAM it up, and fill the mold with hot glue. Wait 'til dried, and remove. Hopefully, your glue won't be flimsy so that it doesn't operate well as a piece. Other fillings may work better, but I have no idea.
*Note: If not, take a chunk of clay, and cut it in half. Push the piece you need a copy of halfway into one chunk of clay, and push the other chunk on top of it until it is even with the other chunk. Then continue to heat it.
Afterwards, when gluing, assuming your piece if small, you can just overflow the first chunk quite a bit and then force the other chunk on top. After the glue is dry, just cut the chunks away from eachother (obviously not cutting the glue) and use a knife to cut away the excess glue arround the mold.
That's my advice...

just google mold making or something

i also found a page where they make lego parts using a rubber mold and ABS plastic as the filler. I used to play with legos when i was younger, found it pretty interesting..

looks like you have to make a container out of legos and pour some liquid mold-making stuff called insta-mold into it. and then after that pour plastic casting resin into the mold. I'm going to check this stuff out at an art store tomorrow, if its too expensive then forget it

Theirs might come out better, but our way is hella cheaper.
You might even try melting down whatever fill your'e gonna use, then letting it dry. (Like melt the hot glue so it is a pure liquid)

its made from a piece cut out from a 1 1/2 inch pvc coupler and a plastic propeller from a tiny motor which I cut to shape and epoxied it on the pvc.
