This is based this on a few screenshots from the movie, which means it's correct for one scene, but may not be correct for all scenes, since animators sometimes take creative liberties when sizing items. Once assembled, it shoudl be about 30" tall.

Parts are broken out so you can print everything in their actual color. You'll need supports on the center section where the gauge goes. Exploded view photo shows where all of the parts go.

Text on side and top of canister are embossed, so you can just use a black paint pen for those instead of making decals, stencil or rub down type. You'll need to find your own caution stickers for the canister.

I have included several versions of the red gauge.

Version 1 is just a large red cylinder for those of you who can't print clear parts.

Version 2 is a red cylinder with a solid clear cover (for those of you who have a SLA/DLP to print clear).

Version 3 is the clear cover broken into sections with grey progress bars (again the clear is for SLA/DLP printers). You'll have to print 6 of the grey bars to insert between the clear sections.

There are several heights of the red progress cylinder for version 2 and version 3 gauges.

You should be able to drill holes in the back of the gauge back panel to add LEDs if you want.
