AD5X Tool Holder Remix with Expanded Storage

This is a remix of the AD5X tool holder that combines elements from the original model and related remixes, with the goal of making the layout more flexible and less tied to one specific glue size or tool arrangement.The main changes were widening the overall body, enlarging the glue holder, expanding the general utility storage area, and replacing 4 of the 6 smaller Allen/tool slots with 1 wider slot so the Allen wrenches can stay in their original holder/clip. I also removed the nozzle size labels to make room for the expanded sections.I did not make enclosure-specific geometry changes, so this version should still be usable with the AD5X enclosure setup.
