⚙ Print-in-Place

PRINT-INPLACE

Mechanisms that emerge from the printer fully assembled. No glue, no hardware, no assembly - just lift off the bed and use. Every clearance spec is verified through physical stress-testing.

MECHANICAL DESIGNS

Roll With It - Portable Dice Roller

A fully enclosed dice tumbler that prints complete with internal tumble chamber. Shake and place on the table. Tested with d4 through d20. All clearances verified at 0.2mm.

Roll With It - Hex Grip Edition

Same mechanism with a textured hex exterior grip for confident one-handed shaking. Two-color filament swap available. The grip texture is designed to prevent table-edge rolls.

One-Handed Page Master

A book page holder that clips to any page thickness. Articulated spring mechanism prints in one go. Squeeze to open, release to hold. Tested on paperbacks, textbooks, and tablets.

Carry 10 Bags - One Hand

An articulated handle that locks grocery bags in a load-bearing grip position. The locking arm prints in-place. Tested to 25 lbs of load - two handles back to back handle a full grocery run.

Rugged Universal Water Bottle Clip

A spring-loaded bottle clip that attaches to any bag strap. The spring mechanism is printed in-place. Tested with 32oz and 40oz bottles. Release force is calibrated for single-hand operation.

The Hands-Off Lockdown Cage

A locking mechanism cage - the rotating lock arm prints assembled. Opens and closes with a quarter-turn. Use for desk cable management, tool storage, or as a fidget mechanism.

Print-in-Place Settings

Clearance gaps: All mechanisms are designed with 0.20mm clearance gaps. Do not adjust this. Smaller gaps cause fusion; larger gaps cause rattling.
First layer squeeze: Reduce your first layer squish to 90% of normal when printing print-in-place files. Over-squished first layers can fuse the lowest moving part to the base.
Support removal: None of these files require supports. If your slicer generates them inside the mechanisms, check that your overhang threshold is set to 45°.
Material: PLA+ is the recommendation. Avoid PETG for tight-clearance mechanisms - PETG has more thermal expansion which affects clearance after printing.

🟠

Prusa MK4S

Consistent first-layer squish and dimensionally stable PLA+ output — critical when 0.20mm clearance gaps are the entire design.

🔷

Sovol SV08

Full Klipper config access lets you dial Pressure Advance precisely - useful for the tight 0.20mm clearances these mechanisms demand.
