TL;DR
A ToolGuyd writer reported that his son’s homemade Halloween outfit and electronics-equipped prop were ready for a school costume day, despite a side panel breaking during the event. He repaired it before the evening party and Halloween, and described design and wiring changes he would make in another version.
A ToolGuyd writer said his son’s homemade Halloween costume and electronic prop made it through a school costume day, although a side panel broke during the day and had to be repaired before later celebrations. The account describes a first attempt that pleased the child but left the maker with specific changes in mind for a future build.

The costume included a side panel made from 3D-printed parts, which the writer said had been assembled with epoxy. One side came off partway through the school day. The writer reported that the break pulled apart layers of filament, and said difficulty clamping the pieces during assembly may have contributed. He reattached the panel with CA glue and machine screws ahead of the class party and Halloween.
The prop itself worked, according to the report. Its revised side panel housed electronics, and the build included a seven-pixel LED board with independently controlled RGB colors. A white cover plate diffused and protected the LED element. The access panel held a battery holder, Raspberry Pi Pico 2 mounting points and four switches. The writer used Wago Lever Lock connectors for wire splices, saying time constraints prevented him from refining the wiring with other connectors or terminal blocks.
The writer said the project was completed in time for a school day when children could bring costumes. He had also prepared additional props, but his son either declined them or there was not enough time to use them. The child was happy with the outfit, the account said. The maker described the project as a successful first attempt, while acknowledging that reliability and finish could improve.
A Working Build With Practical Tradeoffs
The report offers a specific example of how a homemade costume project can succeed for its main purpose while still exposing weaknesses in construction. The prop was usable and the child liked it, but a panel failure required a quick repair before the next event. For readers making similar projects, the account identifies a practical distinction between getting a build ready for a deadline and having time to test and reinforce it.
It also shows how deadline pressure shaped design choices. The maker said he left decorative hose brackets in place after running out of time to add the hoses, and accepted temporary wiring arrangements rather than rebuilding them. These are the writer’s reflections on his own project, not a general test of 3D-printed costume construction or a guarantee that the same materials will perform similarly in other builds.

How the Prop Took Shape
The maker revised the side panel from an earlier flat version so it could hold the electronics. He also changed the front cone to a full circle and added a white cover over the LED. Because the enclosure used substantial filament, he said it was easier to iterate on the side panel than to make changes to the full enclosure. He printed test pieces to refine small hole diameters for the switches and other fittings.
The lighting controls were simple: the writer said the power-on state used cyan, while red, green and blue buttons activated their corresponding colors. He tried using AI to generate code for a brightness ramp and then a blinking effect, but said the attempt did not work well and he set it aside. The report does not describe that experiment as part of the finished prop’s working features.
Other planned elements did not make the final version. The writer ran out of time to add decorative hoses, and said he had not modeled the switches and other electronic components. He also had camo pants, a headlamp and a camo face mask for the costume. The report presents these details as part of one family’s project rather than as a commercial product release.
“For a first attempt, it worked. But if I had more time I could have made it more reliable.”

Which Improvements Will Make the Next Version
The report does not say whether the writer has begun a new version or confirmed when one will be made. His proposed changes—including narrower shoulder straps, a different angle, mechanically joined left and right sides, and a connector to make electronics removable—are ideas for a later iteration, not completed modifications.
It is also unclear exactly how much the clamping difficulty contributed to the panel breaking. The writer suggested it may have played a role, while describing the break as damage to layers of filament. No further testing, measurements of the joint’s strength, or comparison with other assembly methods were provided. The account does not report injuries or other consequences from the break.
Possible Revisions After the Holiday
The writer said he may work on a more refined update after the new year, but did not commit to a date or a particular final design. He identified several possible changes: attaching the LED module directly to the enclosure, adding a connector for removable electronics, and moving electronics toward the bottom to free side panels for decoration.
He also said he might explore translucent cast acrylic for decoration and add more lighting effects, sensors or sound. Those possibilities remain ideas rather than announced features. The next confirmed development, if one is published, would be the writer’s follow-up on whether he revises the prop and how the proposed design changes perform.
Key Questions
What happened to the Halloween costume project?
The ToolGuyd writer said his son’s costume and electronic prop were ready for a school costume day. One side panel broke during the day, but the writer repaired it before the evening party and Halloween.
How was the broken side panel repaired?
The writer said he used CA glue to reattach the panel and drilled holes to secure it further with machine screws.
What electronics were in the prop?
The account describes a seven-pixel RGB LED board, a Raspberry Pi Pico 2 mounting area, a battery holder and four switches. The writer said the buttons controlled basic color states.
What changes might the writer make?
He listed possible changes to the panel joints, straps, LED mounting, removable electronics and interior layout. He said a more refined update might come after the new year, but gave no confirmed schedule.
