Improved Allen Wrench / Hex Key Holder Parametric with Labels

thingiverse

Update 5: Code cleanup complete! Now possible to flip text using variable. Slope positioned at bottom should make key insertion easier and removal harder, so model needs flipping. Added toggle for angled or straight groove as in original design. Standard Set STLs now corrected (original didn't include #9 and had extra #3.5 not standard). Inch sizes: 1/20, 1/16, 5/64, 3/32, 7/64, 1/8, 9/64, 5/32, 3/16, 7/32, 1/4, 5/16, and 3/8 inches. Metric sizes: 1.5, 2, 2.5, 3, 4, 4.5, 5, 5.5, 6, 7, 8, 9, and 10mm. Optional setup to enter own wrench sizes as array for custom holder with labels included. Generous upper chamfer should prevent support needs; however, this may impact O-ring, which remains untested! Example STL rendered for: 10, 8, 7, 6, 5.5, 5, 4.5, 4, 3.5, 3, 2.5, 2, and 1.5. Warning: This model has not been printed or tested; it is marked work in progress. Comments welcome! Update history: Update 4: Size compensation added back to code after being lost during previous update. Holes should be oversized for o-ring retention, not tight plastic. Update 3: Numbering moved to side bottom edge for better z-resolution printing. Update 2: Font size increased and spacing adjusted for larger numbers with 0.4mm nozzles. Imperial version added; however, code could not be combined into single file due to array reassignment limitations. Second array provided for manual text entry in imperial mode.
