About this 3D model

Helical swivel bit storage. You might want to apply grease or lube for storage tabs above first one, so bottom doesn't turn or doesn't turn easily. See my instagram for video https://www.instagram.com/p/CLlDt0grsYS/ Bottom tab should have heavier items for stability. If placed on metal bench or shelf, I recommend putting a strong magnet to bottom tab so it won't topple. Update: For pillar bottom, I added a circular stabilizer. If you mount the pillar on it, you don't need to worry about toppling anymore.
