This is a remix of Chewey's deburring tool case and Whity's parametric rugged box. It has an insert construction in the style of PjotrStrog's Multipart Pinecil case.

Like the original, this case fits a 150mm length tool from tip of blade to end of handle and has the sturdy blade holders. The handle width is 15mm across (widest) edge of the hex handle.
 

For people having issues with the blade holders breaking, I've added a version of the top insert which has separated blade holders. The blade holders are printed in a better orientation for strength, but need to be glued in place on the insert. See last photos for details.

You will need six 20 mm long M3 screws to assemble it. The magnet used for holding the tool in place is 6mm x 3mm. 

Super glue can be used to hold the magnet and inserts in place if the friction fit is not strong enough.
