Spirit Giga Meter Appearance Upgrade Kit

Printing, fitment, finishing, and installation notes for the Spirit Halloween Ghostbusters II Giga Meter.

Use this guide with the current STL/3MF appearance-upgrade collection. The designs are reference-inspired interpretations made to fit the Spirit version of the prop.

01

Fit first

Test-fit each part before paint, adhesive, or permanent finishing.

02

Print thoughtfully

Use the baseline FDM settings below and protect visible faces from support marks.

03

Finish your way

Paint or texture the parts to match your display build and preferred interpretation.

Before you begin

Confirm the scope and gather your tools

Power off the prop before working on it. The notes below describe the current appearance collection; they do not claim that every detail is an exact screen-used reproduction.

Current collection

  • Rear heatsink with ten fins
  • Contoured main-body side pads and tapered pieces
  • Handle tread, including a shorter fitment variant
  • Front-display axles / spindle details
  • Front-display side nubs
  • Left-side switch and Ghostbusters-inspired knob variants

Printing

Baseline print recommendations

These are starting points for the current designs. Confirm your slicer preview and test-fit before committing to a full set.

1

Use a fine layer height

Print most parts at approximately 0.16 mm layer height with around 15% rectilinear infill.

2

Improve visible faces

Enable ironing where your slicer and orientation allow it. A smooth build plate can improve the finished face of FDM parts.

3

Orient pads face down

Print most pads face down on a smooth plate where practical. Protect the visible face from support marks and choose supports that are easy to finish.

4

Choose material for the part

Use a finer-resolution FDM print or resin when that better suits the part and your finishing workflow.

5

Form the handle tread carefully

PLA or TPU are possible material choices. After printing, use gradual controlled heat to form the tread to the handle. Avoid scorching, distortion, and burns.

Installation

Fit the collection to the Spirit Giga Meter

Part names below match the files currently present in the project folder. Work through the collection one area at a time.

1

Inspect the stock prop

Photograph or note the original orientation of the display, handle, rear panel, and side surfaces before removing or attaching anything.

2

Test-fit every printed part

Check the part against the Spirit body and neighboring details. Confirm that shell seams, screws, lenses, handles, and battery access remain clear.

3

Install the side pads and tapered pieces

Use the contoured side pads and the left/right tapered pieces to build the layered body profile. Match the contours before choosing an attachment method. The project notes do not prescribe one adhesive or hardware set, so test the material and reversibility you want on your own build.

4

Add the rear heatsink

Align the ten-fin heatsink with the rear panel. Its multiple angles are intended to follow the Spirit body rather than a perfect triangle, so check the fit across the full contact surface.

5

Fit the display axles and nubs

Use the front-display axle/spindle details and side nubs to add mechanical surface detail. Compare the left and right sides before final attachment.

6

Choose the left-side variant

The collection includes a switch-style detail and a separate Ghostbusters-inspired knob option. These are functionality-inspired cosmetic interpretations unless you deliberately adapt one for a working control.

7

Heat-form the handle tread

Warm the printed tread gradually with a heat gun and check the fit often. Keep the heat moving, protect the prop and your hands, and stop before the print softens more than needed.

8

Finish and inspect

After the fit is confirmed, finish the parts as desired. Check that the display, lens, handle, body seams, and controls still operate or access as intended.

9

Document your final build

Keep your unused variants and revision notes together. Photograph the completed prop so future fitment or finish changes are easier to reproduce.
