Diameter changeable screwdrivers and tools holder

A tool holder that can be printed in one piece with different sizes of sleeves from 2mm to 20mm. Just cut the very thin joints with knife, or just push the sleeves out with finger, the diameter of the hole can be changed to fit different tools, screwdrivers, pens, tweezers, syringes, drills, all can be placed according to your organisation. If you have more tools that need to be stored, you can also print multiple holders and then connect them with dovetails, which are included in the print file!Finally, if the sleeve joint breaks, or if you want to reduce the size of the hole in the future, just put some tape on the back to hold it in place. Simple and you can't see it on the back anyway.
