Elegoo Centauri Carbon - Opencentauri Community CAD model

Also available through the opencentauri CAD github
Live interactive model you can link into Fusion 360 on the Opencetauri Docs.

Community Centauri Carbon CAD model with many contributions from in the Opencentauri server as well as others. Elegoo has provided official CAD models for XY and Z motion system components so the model is functionally complete with the exception of small things and the top plastic insert!

Clarifying the license- For any users who have contributed models to the project as noted below you would need to contact them. The model is generally licensed under GPL V3, so attribution is required for reuse of the model, however I generally do not consider this to apply to simply using this CAD for reference dimensions, but if you use this geometry in your final product attribution should be provided to the opencentauri project.

This model took a while to make and integrate- if you found it helpful consider buying me a coffee!

• Elegoo generously provided official models for Z axis, X axis, and toolhead plastic parts, frame, and display.

• Anna/Devminer provided mainboard and toolhead board models

• MakingStuffandThings: spool holder

•  Indi001 (artstation profile) provided the toolhead interface cable chain link CAD

• userMINUS_Stl provided main cable chain link cad

• clogged_nozzl3 provided the XY belt tensioner

• thijskunst added beta opencentauri board model!

Deprecated/replaced component contributions essential to building up to this model: 

• Lamark Did a massive amount of work to produce a high accuracy model of the toolhead cowling and toolhead board! Also provided fantastic purge shoot model.

• Heartforge/Bandit provided an accurate rear bed mounting model

• Benjamin Butschell kindly allow use of his improved midcowling model- Please check out his model and consider supporting him! 

• Geometry from Felix Oberfeld's toothed idler block mod geometry used to improve this model. Consider downloading- toothed idlers are much better than smooth!

• cornflakes generously provided CAD for the front Idler mounts.

Changelog

• 5/12/26 V150  Update:  Added official frame and display model from elegoo and refined other component CAD accordingly, revised top insert, added Opencentauri board beta CAD, added bed SSR board, added cosmos splash screed, added z-axis optical endstop, added strain gauge and accurate bed shell model

• 2/9/26 V120  Update:  Added more detail on top insert, added filament detector, added spool

• 12/21/25 V100🎉 Update:  Major revision from multiple authors, added official elegoo model files. full z alignment complete

• 11/9/25 V62 Update: Ported in overhauled toolhead model and rear bed mount model, moved Z axis, revised front bed mounts. Z axis alignment and front bed mounts still have some alignment issues that need to be worked out but it is more accurate than previous versions. Mainboard and toolhead board models added

• 10/15/25 V57 Update: Ported in improve geometry for gantry parts as noted above. Improved cosmetic features of front cover.

• 8/29/25 V54 Update: fixed mounting hole positions in top die cast frame, added channels for cables, improved rough cad for plastic top. Added IGES file for solidworks

• 8/25/25 V52 Update: Improved extruder and toolhead accuracy, added higher accuracy midcowling. rebuilt assembly architecture, Probably a lot of other things I forgot.

• 7/27/25 V41 Update: Extruder CAD and top die cast frame done, refined toolhead carriage, added Refined and/or added XY axis motor mounts idlers and xyjoints- but they are only mirrored so one side does not acount for proper belt routing right now.

•  7/24/25 V37 Update: Added mounting points for lower panel, z belt, electronics, screen

•  7/21/25 V30 Update: Added draft angle on die cast bottom, cutouts on bottom panel, lower z rod mounts, leadscrew pulley and bearings, z motor, and lower holes for the screen, electronics compartment details

• 7/20/25 V25 Update: Bottom panel, deck panel with mounts for electronics and z pulleys added, more details on rear panel added, rear z bearing holder added, bottom frame details and feet added, added more accurate door spacer and trim for glass panels, added many fasteners.

• 7/19/25 V16 Update: Magnetic closure for door added, Aux fan module added, toolhead fan duct and cowling refined

• 7/18/25 V8 Update: Panel geometry detail added, add handles and door hinges, improve XY joint accuracy.
