Here's a mini rack for a grow-lamp to help indoor kitchen-plants to evolve :-) Due to the lack of a sunny-side window and the general amount of sun in northern germany X-D
I use a Romberg "Aromatic" for the plants ("Mia" works too), an E27-lamp mount from "Conrad", some small wooden planks (11x5 mm) and a red/blue-led-bulb to speed up my basil-income ^^
Lengths for the wood-pieces are: top - 4.2 cm and 32 cm; sides - 30 cm (75° angles at the bottom). I fixed the mount with 2 M2 screws i had lying around, because the initial thin arms on the side broke off (deleted them in the model, works anyways).
Depending on your printers accuracy some minor sanding of the wooden ends may be necessary.
Just wanted to spread the idea of building a cheap sun-alternative ;-P
