I don't seem to care what measurement the actual or model is made in. If I have a 32meter boat, and I want it in 1/72nd scale, then, 32m ÷ 72 inches = 17.49" Okay, cool,... a 17.5" long model. Now, Lets say I have plans that are 7.375" long. I need a factor for enlargment. 17.5 ÷ 7.37...

Using just a resistor will fail. Typically there will be too much amp draw, and the heat will kill the resistor, and the circuit will die. Use a simple LM317 adjustable regulator and build a little voltage regulator for the job. Also leave room for a heatsink and venting, even it gets a bit warm. ht...

Wrap your styrene around a slightly smaller wooden dowel, then
rubber band it and leave it over night. That should put a curl into
it and make it easier to form.

Really, any plug will do what you want. But most of them will not be a good structural connection to hold the model rigidly in place. Stereo headphone jacks will be fairly rigid, but it will allow the model to spin. The micro plugs and others of that size won't spin, but they won't support the model...

Metal like resin often has oils on it from the forming process.
It is best to wash it, and the sand it with some 320 grit sand paper.

Do this, and you will probably find that the greebly will go on, and
stick instantly,... exactly where you don't want it.

You would have to do some experiments, to see what
viscocity of glue will hold the height and dimension of
your buttons. CA, elmers, canopy glue all dry fairly clear.

I had issues with polyester resin not playing well with silicone molds, shrinking too much. The silicone was somehow inhibiting the cure, when the part shrank, it would hang sticky threads on the mold as it shrunk, and these would drop on the part and make a horrible mess.
