Join two small foam-board panels at 90 degrees for tabletop lighting. Two open connectors align separate board edges at a right angle without metal hardware. MEASURE FIRST Light foam-board panels up to 60 × 100 × 3.0 mm. Channels 3.6 mm wide and 25 mm long. Lower connector open through to the table; upper cap seats 13 mm over the top edges. IN THE BOX 2 printed parts in matte black PLA: joint-a, joint-b. Additional items required: Two small foam-board panels, not included. No additional fasteners required. Subjects, camera, lights and accessories are not included. Printed and shipped on demand by Slant 3D. Shipping and taxes are calculated at checkout. USE Place the connector with through-slots on a level table. Insert the panel edges through it so both panel bases rest on the table. Turn the capped connector upside down and lower it over the top edges. Use two equally tall lightweight panels and confirm stability before photographing. No suspended or overhead use. Dry indoor use. Keep away from heat; inspect and smooth any rough print edges before use. CAD geometry and local slicing checked. Physical fit, finish, stability and durability have not been tested. Images are renders of the actual CAD. Design: João Lutz / JoaoLutzFilm, developed with AI assistance. Original CAD; no third-party mesh used.
