Autoclave Cassette Clips & Dividers (STL Model)

Upgrade your sterilization workflow with ultimate clinical precision. The Premako Universal Autoclave Cassette Clips & Dividers are high-performance, 3D-printable replacement and custom organization modules designed for dental and medical instrument cassettes.

Standard silicone inserts degrade, discolor, and lose their grip over time, while generic metal dividers can scratch delicate titanium coatings on scaling and diagnostic tips. This STL package provides a robust, geometrically optimized solution to securely lock your hand instruments in place through thousands of sterilization cycles.

Engineered Compliant Mechanism Design
When printing for clinical environments, you cannot rely on standard elastic materials that melt in high heat. This system is engineered using a rigid compliant mechanism, utilizing advanced geometry rather than material stretch to create a smooth, secure snap-fit.

Made for a standard Ø8mm to Ø10mm instrument handles.

Universal Cassette Integration (The Snap-Foot)
The underside of these modules features a highly calculated, split-leg T-Anchor mounting profile designed to “impregnate” seamlessly into industry-standard internal cassette rails.

Standard Rail Compatibility: Calibrated for standard 4.0mm punched or laser-cut rectangular slots.

Flanged Anti-Rock Shoulder: A wide upper shoulder flares out over the rail to distribute downward forces evenly, preventing the clip from rocking or tipping when instruments are being rapidly snapped in or out.

Material & Sterilization Guidelines
These models are strictly optimized for high-performance, medical-grade additive manufacturing:

100% Autoclave Compliant: This geometry is tailored specifically for high-temperature advanced filaments like PEEK, PPSU, or PEI (Ultem). When printed with these polymers, the clips can withstand repeated Steam Autoclave Sterilization cycles (134°C / 273°F) and harsh enzymatic cleaners without warping, shrinking, or losing their mechanical snap memory.

Chemical Disinfection (Lab/Office): Can alternatively be printed in PETG for standard non-autoclave lab storage or cold-sterilization chemical wipe protocols.

3D Slicer Optimization Notes
To guarantee the structural longevity of the snap-fit legs and avoid mechanical shearing along layer lines, follow these exact slicing parameters:

Print Orientation (Critical): Always print the clips on their side. Printing them sideways ensures that the continuous filament paths run vertically down the anchoring feet, maximizing tensile and flexural strength where the clip experiences the most stress.

Wall Generator: Use the Arachne Engine to maintain crisp, continuous toolpaths around the 1.0mm thick anchoring legs and compliant tabs.

Wall Loops: Set to a minimum of 4–5 perimeters to ensure the flexible fingers and mounting feet are printed completely solid for maximum spring-back velocity.
