A ToolGuyd contributor says a homemade Halloween costume and illuminated prop were ready for a school costume day, and his son was happy with the result. A costume assembly broke during the day; the maker repaired it with glue and machine screws before later events and outlined changes for a future version.
A ToolGuyd contributor says his homemade Halloween costume and electronic prop were ready for his son’s school costume day, despite a side panel breaking during the day. He reattached the piece before the evening class party and Halloween, and said his son was happy with the result.
The costume assembly joined printed pieces with epoxy. According to the report, one side separated from the bottom partway through the school day, with the break tearing through layers of filament. The maker said clamping the parts together had been difficult and may have contributed to the failure. The costume remained usable, and the child still had most of the outfit and its prop.
Before the later events, the maker used cyanoacrylate (CA) glue to reattach the side panel, then drilled holes and added machine screws for extra support. He described the result as adequate for a first attempt, while saying it could have been made more reliable with additional time. His son did not want changes to the long shoulder straps, so those were left as they were.
The prop combined a 3D-printed enclosure with a seven-pixel LED board, a Raspberry Pi Pico 2, a battery holder and four switches. The maker used Wago lever connectors for wiring splices and said he did not have time to refine the wiring with dedicated connectors or terminal blocks. A battery holder proved unreliable, prompting a replacement and a redesigned bracket. The report does not provide a cost, build duration or detailed testing results.
A School-Day Test for the Costume
The account offers a practical example of how a homemade costume can fare under real use rather than just during assembly. The side panel failed during a school day, but the repair allowed the costume to be used again for the evening party and Halloween. For readers making similar projects, the report points to joint strength, clamping and mechanical reinforcement as issues that can matter when printed parts are worn or handled.
The prop also shows the trade-offs involved in finishing a custom electronic build against a deadline. Its lights and controls worked well enough for the occasion, according to the maker, but rushed wiring and a problem with one battery holder left potential improvements. The source is a personal project report, not an independent product test, and it does not establish how durable the costume or electronics would be over repeated use.

Printed Parts, Lights and Last-Minute Changes
The maker designed a revised side panel to house the prop’s electronics after an earlier version consisted of a flat panel. He also changed the front cone to a full circle and added a white cover over the LED element to diffuse and protect it. Because the cone shape meant the prop had to be set down facing upward, its form affected how it could be handled.
Some planned decorative details were omitted when time ran short. The maker left brackets in place where hoses had been intended, and said he barely finished soldering before the deadline. He also made changes during the build, including the LED cover, without modeling every switch and electronic component first. The report says the child wore camouflage pants and sometimes a headlamp and face mask; other proposed props were either declined or could not be made to work in time.

Durability and Future Changes Remain Open
The report does not say whether the repaired side panel was tested over a longer period or whether it remained secure through all later wear. It also gives no independent assessment of the epoxy failure, and the maker presents difficult clamping only as a possible contributing factor. The exact cause of the break is not confirmed.
Several proposed changes are ideas rather than completed work. The maker said he might narrow and flatten the shoulder straps, redesign the joint between the printed sides, mount the LED directly to the enclosure, and add removable connectors. He also considered relocating electronics inside the enclosure and using translucent cast acrylic for decoration. The report does not confirm that any of these changes will be made.
Possible Revisions After Halloween
The maker said he may return to the prop after the new year, but gave no firm schedule. A future version could include stronger mechanical connections, a more serviceable electronics layout and tidier wiring. He also mentioned adding effects that respond to sensors or sound, while noting that those features might become a separate build.
For now, the confirmed outcome is limited: the costume was repaired in time for the evening events, the prop was used, and the maker’s son was happy. Whether the project receives another iteration—and what changes it would include—remains undecided.
Key Questions
What happened to the Halloween costume?
A side panel in the costume assembly broke during the school day. The maker said the break tore through layers of filament; the costume and prop were still usable.
How was the broken panel repaired?
The maker reattached it with cyanoacrylate glue and drilled holes to add machine screws before the evening class party and Halloween.
What electronics were in the prop?
The prop included a seven-pixel LED board with RGB controls, a Raspberry Pi Pico 2, a battery holder and four switches, according to the project report.
Will the maker build a revised version?
He said he might work on a refined update after the new year. Possible changes were discussed, but no follow-up build or schedule was confirmed.
