Capture nostalgic charm with this 3D printable lightbox featuring a vintage Mazda sign. The design includes both standard stands and a special pole to mimic the iconic roadside signs. Perfect for car enthusiasts and vintage sign collectors, this lightbox brings a touch of classic automotive history to any space.

If you don't have or don't want to install LED's you can just glue the parts together and have an awesome sign!

WARNING!

• remove purge line at the beginning of the print, it may interfere, specially with bigger prints!

Materials and tools:

• glue gun
• aluminum tape
• led strip: simple 1m or 2m white or rgb led USB (recommended 60 LED per meter)
• soldering iron (optional)

RECOMMENDATIONS

• use a textured PEI sheet

• remove purge line at the beginning of the print!

• use the print profile, it has quite a few setting changes that help achieve the best results

• make a hole for the USB strip wherever you like it best with a soldering iron, drill or in the slicer

• use the aluminum tape on the inside of the backplate to help with light diffusion

• glue the LED's the further away from the colored design possible; placing them too close ruins the diffusion and the individual LED's become visible

Bambu Studio Settings: I always recommend using the print profile I provided since it has settings with which I've been able to get the best results. If you choose not to here are the main slicer settings I recommend:

• preferences (ctrl + P) → activate developer settings → Quality →Advanced → First Layer Flow Ratio: 1.04 to 1.08
• Quality → Wall generator → Arachne
• Quality → Wall transitioning threshold angle → 30º to 50º
• Strength → Advanced → Infill/wall overlap → 20% to 25%
• Increasing retraction / reducing temperature can help reducing wisps
• Order color printing from lightest to darkest color
