New Design Released
The new hex key handle has been enhanced with the following features for improved usability and style:

• Size Indications Added: Responding to popular requests, size indications in millimeters have been added to both the cap and the handle.
• Secured Handle: By securing the hex key on the handle side, the handle cap no longer loosens when you are loosening screws.
• Consistent Handle Size: The handle size is now uniform across all hex key sizes.
• Even More Stylish: The design is more elegant than ever!

These improvements enhance both usability and aesthetics. Please check out the new design page.

------------------------------------------------------------------------------------------

My design ensures that the handle grip doesn't obstruct the use of the short arm, and the short arm's position does not interfere with the hand gripping the handle.

Allen key handle for M1.5, M2, M2.5, M3, M4 and M5 keys.

Print Settings:

• Material: PLA, PETG
• Layer height: 0.20mm
• Supports: No
• Perimeters: 2
• Infill: 15%
• Brim: Outer brim 3mm

Notes:

• Recommended use brim to prevent peeling from the print bed.
• I confirmed that 0.6mm nozzle with 0.30mm layer height works fine.
• The 'M' in the context of screws does not indicate the diameter of the Allen key, it refers to the nominal diameter of the screw itself.
