aquarium light stand

needed a light stand for my very make shift aquarium lighting so i made this (it works well though may not be suited for most people )it takes a 3.5 cm bar/piece of wood in my case (also i used super glue and a 3d pen to glue them together both of which im not good at so it looks realy rough in my case) this is only because i have a tiny printer and cant print the pieces in 1 go
