About this 3D model

Riser to add enough height below Ikea's Gorm series storage racks for a roomba to make it under the bottom shelf. Without the riser, the first floor is just over the ground. If you put the shelves in the second rung there's a good 1.5-2" more than necessary. This riser gives room plus about 0.5" of extra clearance without sacrificing precious storage space. Holes for drainage keep the wood dry and rot free, four nubs create a snug friction fit. Suggested to print with PLA+ with Strength settings. Likely works with Hejne Series too (with a bit of extra space) but I haven't tested it.
