About this model

Give your drill/driver/screwdriver bit extensions a little home . This holder gives three 1/4″ hex-shank extensions their own spots, arranged shortest to longest. Each sits at a different depth, so the top ends are easy to grab instead of disappearing into a tube. Boost MeIf you like my models, I'd appreciate a boost! The lid is friction fit - no magnets, screws, or assembly required. The default model/profile fits my 60, 100, and 150 mm extensions. The model is fully parametric and modifiable (designed in OpenSCAD) - for a different set of extension sizes, enter your measured shank lengths and cylinder size in the customizer - and please upload your print profile, that'd be awesome! Print notes: Print the body upright (holes up) with a brim, and the lid upside down (flat roof on the bed).…
