Aachen Maker Meetup #161: 3D-Printed Train Parts, Bug Traps, and Creative Lighting Solutions

Thorsten showcased a 3D-printed bogie for a model railway at a scale of 1:29, alongside a miniature bridge model suspended by filament strands.

Additionally, Thorsten presented a 3D-printed differential, highlighting the precision and mechanical complexity achievable with 3D printing.

To add a touch of realism to his model train setups, Thorsten has developed LED circuit boards that simulate the flicker of fluorescent lights, bringing a lifelike atmosphere to his railway scenes.

David's contribution to the meetup was both inventive and practical. He presented a fruit fly trap that uses a light barrier sensor in combination with an arc generator from an electric lighter. The system is designed to automatically activate the arc when flies pass through the light barrier, offering a unique and high-tech solution to an everyday household problem.

Martin, known for his diverse 3D printing projects, brought a custom-printed computer case for a NAS (Network-Attached Storage) system. The case not only serves a functional purpose but also reflects the growing trend of personalized tech solutions made with 3D printing.

Michael introduced a charming and practical 3D-printed mini lamp, complete with its own custom PCB. The lamp is dimmable and rechargeable, intended as a cozy night table lamp that can fit inside a jar—such as a repurposed jam jar—offering a creative blend of functionality and aesthetics.

In a lovely addition to the technical projects, Rüdiger and Nitzan surprised the group by bringing homemade cake, contributing to the warm and collaborative atmosphere that is a hallmark of the MakerMeetup.

Once again, the MakerMeetup brought together a fascinating array of projects. From creative uses of 3D printing to practical household solutions, the meetup fosters a collaborative environment where innovative ideas and personal projects are shared and celebrated.
