Keep your high-speed, low-speed, and laboratory burs perfectly sorted, protected, and ready for action. The Premako Modular Bur & Drill Bit Organizer is a high-precision, 3D-printable storage solution engineered specifically for the rigorous demands of modern dental clinics and labs.
Say goodbye to generic, oversized bur blocks where bits wobble, fall out, or slide completely out of reach. This system is meticulously modeled around exact dental shank geometries to deliver the ultimate “snap-in-place” workflow efficiency.
Engineered Around Real Clinical Dimensions
A truly universal bur block cannot rely on a “one-size-fits-all” depth. Different handpiece burs require exact engineering constraints to remain stable while leaving enough neck exposure for a quick, ergonomic grasp.
This digital package features three distinct, meticulously calibrated module configurations:
The FG Module (High-Speed): Calibrated with a 1.8mm hole diameter and an exact 10.5mm pocket depth. Optimized perfectly for Friction Grip burs so they remain rock-steady without sinking, leaving the functional head perfectly accessible for fingers or tweezers.
The RA Module (Low-Speed / Latch-Type): Engineered with a 2.55mm hole diameter and a 12.0mm pocket depth. This completely conceals the mechanical latch notch of right-angle burs while presenting them cleanly.
The HP Module (Laboratory / Straight Handpiece): Built with a 2.55mm hole diameter and a deep 24.0mm pocket depth. This prevents extra-long, top-heavy lab trimming burs from tipping over or tumbling out if the tray is bumped.
Micro-Funnel Entry: Every single hole features a built-in 0.3mm x 45° internal chamfer. This acts as a microscopic funnel, allowing dental assistants to drop burs back into their slots seamlessly without catching on layer lines.
Zero-Pooling Fluid Drainage: Includes a tiny integrated escape port at the base of the pockets to ensure ultrasonic cleaning fluid or cold disinfectants drain completely rather than pooling at the bottom.
High-Performance Material & Sterilization Compliance
This model is optimized for advanced, medical-grade slicing and printing:
Autoclave-Ready (Clinical): Slice and print using high-performance engineering polymers like PEEK, PPSU, or PEI (Ultem) to allow the loaded bur blocks to go directly into steam sterilization cycles (134°C / 273°F) without warping or losing dimensional accuracy.
Lab-Side Ergonomics: Print in high-flow PETG or PETG HF for high chemical resistance against everyday clinical wipes and disinfectant sprays on your laboratory benches.
Slicer Engine: Optimized specifically for the Arachne Wall Generator to ensure hole walls are printed as strong, solid perimeters.
Wall Loops: We recommend a minimum of 4–5 walls to ensure maximum structural density around the bur pockets.
Infill: 20% Gyroid for premium internal structural stability.
Design & Printing Pro-Tips for UV Sterilization:
If you or your clinical customers plan to utilize UV-C sterilization chambers ($254\text{nm}$ wavelength) for our dental holders, keep these critical engineering guidelines in mind to maximize hygiene and print longevity:
– Opt for PETG HF (High Flow): When printing on high-speed setups, choose PETG HF over standard PETG. Its specialized flow modifiers allow the plastic to fuse much more fluidly. When combined with the Arachne Slicer Engine, the perimeters meld together tightly, leaving almost no micro-ridges or “shadow zones” in the layer lines where bacteria can hide from UV rays.
– Avoid Clear or Translucent Filaments: Transparent filaments can refract or scatter UV light unpredictably rather than absorbing it cleanly across the structural boundaries. Stick to solid, opaque dental colors—like medical grey, deep blue, or matte black—to ensure maximum surface energy absorption.
– Account for Material Aging: Standard PETG is not inherently UV-stabilized. Over months of continuous, high-intensity UV-C cycles, the polymer chains will undergo slow photo-oxidation. Because these are low-stress tool holders, a slight color yellowing or gradual embrittlement won’t affect daily performance, but expect to re-print your operatory suites every 12 to 18 months for peak mechanical fresh-ness.
– The “Hybrid” Disinfection Protocol (Critical): UV sterilization is strictly a line-of-sight technology—the light cannot sterilize what it cannot physically see. Because bur blocks and material trays feature deep internal pockets, the UV bulbs cannot reach the very bottom of the slots.
The Recommended Workflow: For absolute clinical hygiene, always spray or wipe the holder down with a standard surface disinfectant (like Cavicide) first. Allow the fluid to pull any trapped bioburden out through the built-in drainage holes, and then place the holder into the UV chamber to sanitize the high-touch exterior handling surfaces.
