3D printable drill bit index
Thirteen graduated bores from 2 to 8mm, tilted so the bits stay put.
- · 2 to 8mm in 0.5mm
- · 13 bores
- · 150 x 50mm
Printing a drill bit index
The brief above is already loaded into the studio. Edit any dimension in the text — wall thickness, hole diameter, overall length — and re-solve. Every result is checked against a 1.6mm minimum wall and 0.8mm minimum feature size, so it survives contact with a real nozzle. PLA at 0.2mm layers with 20% infill handles most of these; anything that takes load or lives outdoors is better in PETG.
Common questions
Can I resize it? Yes — edit any dimension in the brief and re-solve. The part is rebuilt parametrically, not scaled.
Is the STL print-ready? Every download is a watertight binary STL in millimetres, ready to drop into any slicer.
What material? PLA at 0.2mm for most parts; PETG for anything under load, outdoors, or warm.
