I wanted my modded Mini to be as clean as possible but with a possibility to store some frequently needed tools (like hex keys, nozzle wrench and spare nozzles) with it.
So I came up with the idea of a glovebox style stowage device attached to the left Y extrusion. Lids can be mounted optionally.
Be aware that with the lids mounted the boxes should not be opened during printer operation because the lid could interfere with the Y carriage.
The hinges provided as stl are attached to the y extrusion using drop-in T-nuts M3 and M3x8 hex screws.
Print the boxes upside down, it worked for me without any support.
The lids also upside down and the hinges rotated to the side.
