Drill Bit Sharpener for Bench Grinder – 3D Printed

The jig holds the drill bit at a fixed angle relative to the grinding wheel, making it easier to achieve symmetrical cutting edges and a proper point angle, even for beginners.Included AttachmentsThis design includes three separate angle attachments to cover the most common drill point geometries:90° – for soft materials and plastics120° – standard general-purpose drill bits135° – ideal for harder materials and reduced walkingSimply swap the attachment to match the desired drill bit angle.FeaturesDesigned to mount securely on a standard bench grinderFixed-angle guides for accurate and repeatable sharpeningSimple, robust design optimized for 3D printingImproves repeatability and extends drill bit lifeIdeal for workshops, garages, and maker spacesPrinting NotesPrint in PETG or ABS for better heat resistance (PLA may soften near the grinder)No supports required (adjust if needed)Recommended infill: 30–50% for strength and durabilityUsageSelect the desired angle attachment (90°, 120°, or 1
