Here are 4 different hex key holders that can be printed in vase mode to save time and filament.
11 metric keys: 1.5, 2 , 2.5, 3, 4, 4.5, 5, 5.5, 6, 7, 8 [mm]
9 metric keys: 1.5, 2, 2.5, 3, 4, 4.5, 5, 5.5, 6 [mm]
11 SAE keys: 0.050, 1/16, 5/64, 3/32, 7/64, 1/8, 9/64, 5/32, 3/16, 7/32 [inch]
9 SAE keys: 5/64, 3/32, 7/64, 1/8, 9/64, 5/32, 3/16, 7/32, 1/4 [inch]
I have included .stl files, .3mf files, Autodesk Inventor files and g-code print files for a Prusa MK3S+ with a 0.6 mm nozzle. With my setup they each only took about 11 minutes and 2-2.3 m of filament to print.
