0.2mm Layer Height + 0.4mm Nozzle
Everything was designed with these feature sizes in mind.
5 Top Layers + 5 Bottom Layers
To avoid infill on 1mm thick vertical shell thickness and provide thickness around screw holes.
Arachne-only Walls
Some features are too small to recreate with ancient technology.
Don't forget to set shrinkage for ABS/ASA!
Calibrate with a test cube; Shrinkage can be found in the filament settings of OrcaSlicer.

Chassis Inventory & Materials

  • Top Plates

    Mostly decorative, but need some thickness around the screw holes. Show off your printing abilities with a flashy filament.
    5 walls, 25% grid
    Preferred PLA

  • Unibody Chassis

    The chassis should be made from a stiff material, and it does not experience savage heat.
    8 walls, 50% grid
    Preferred PLA

  • Mid Plates

    High-temp material is required because these serve as the motor mounts.
    5 walls, 50% grid
    Preferred ABS

  • Tensioner

    High-temp material is required because this screws directly into the motor.
    5 walls, 50% grid
    Preferred ABS

  • Lemonstruder

    Made of two parts. Experiences compression from the spring, so a drift-resistant material with good accuracy is preferred.
    5 walls, 50% grid
    Preferred CF-PETG
    Backup ABS

  • Risers

    Raspberry Pi mounts to these, and they keep the SKR Pico pinned down. Material doesn't matter.
    5 walls, 50% grid
    Preferred PLA

  • Z-Tensioner

    High-temp material is required because this screws directly into the motor.
    5 walls, 50% grid
    Preferred ABS

  • Gantry Block

    This links the X and Y rails together to create the XY plane. A stiff material, resistant to warping and drift, is ideal.
    5 walls, 50% grid
    Preferred ABS

  • Fan Wire Guide

    No specific material requirements.
    3 walls, 25% grid, concentric top
    Preferred PLA

  • Filament Guide

    No specific material requirements.
    3 walls, 25% grid
    Preferred PLA

Z-Axis Inventory

  • Z-Axis

    Choose any material for this part, just make sure it looks awesome.
    5 walls, 50% grid
    Preferred PLA

  • Bed Bracket

    The bed bracket is made from two parts. A stiff material like CF-PETG would be ideal.
    5 walls, 50% grid
    Preferred CF-PETG
    Backup PETG

  • Bed Holder

    It's really hard to print, it likes to lift off the bed. Keep an eye on this one. The spine can be printed in whatever you want, I recommend matching the tool head materials.
    8 walls, 50% grid
    Preferred CF-PETG
    Backup PETG

  • Spool Holder

    This has a captive nut, so make sure to add a pause! Layer adhesion is important here, so PLA is a good choice.
    5 walls, 50% grid, concentric top/bottom
    Preferred PLA

  • Bed Holder Cups

    Holds up the bed! Print two of these.
    5 walls, 50% grid
    Preferred ABS

  • Spacer

    Drop these into the Z axis to make the screws line up flush with the back side.
    Preferred PLA

Tool Head Inventory

  • Tool Head

    The tool head houses the hotend and thus must be printed in ABS.
    5 walls, 50% grid, outer/inner wall order
    Preferred ABS

  • Clip

    Clips the belt to the tool end. Layer adhesion matters most, so I recommend PETG or PLA.
    5 walls, 50% grid
    Preferred PETG
    Backup PLA

  • Clamp

    No material requirements. Perhaps use ABS to match.
    5 walls, 50% grid
    Preferred ABS
