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

    The top plates are mostly decorative, save for the Lemonstruder. Show off your printing abilities with a flashy filament and upload your results to the photo album.
    Preferred PLA

  • Unibody Chassis

    The chassis should be made from a stiff material, and it does not experience savage heat. Therefore I would recommend PLA.
    Preferred PLA

  • Mid Plates

    high temp material is required because these serve as the motor mounts.
    Preferred ABS

  • Tensioner

    The tensioner experiences some torsion, so a drift-resistant material like CF-PETG is recommended.
    Preferred CF-PETG
    Backup PETG

  • Lemonstruder

    Lemonstruder is made of two parts. It experiences compression from the spring, so a drift-resistant material with good dimensional accuracy is preferred.

  • Risers

    Raspberry Pi mounts to these and they keep the SKR Pico pinned down. The material doesn't matter.
    Preferred ABS

  • Z-Tensioner

    Does not experience much load, but does experience heat from the motor, so ABS is recommended.
    Preferred ABS

  • XY-Spacer

    This links the X and Y rails together to create the XY plane. A stiff material, resistant to warping and drift, would be ideal like CF-PETG.

Z-Axis Inventory

  • Z-Axis

    Choose any material for this part, just make sure it looks awesome.
    Preferred PLA

  • Bed Bracket

    The bed bracket is made from two parts. A stiff material like CF-PETG would be ideal.

    Backup PETG

  • Bed Holder

    This is best printed in CF-PETG and the spine can be printed in whatever you want, I recommend matching the tool head materials.
    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.
    Preferred PLA

Tool Head Inventory

  • Tool Head & Clamp

    The tool head houses the hotend and thus must be printed in ABS. The clamp is a small part that holds the wires in.
    Preferred ABS

  • Clip

    Clips the belt to the tool end. Layer adhesion matters most, so I recommend PETG or PLA.
    Preferred PETG
