The V-CHONK: A compact CoreXY 3D printer for enthusiasts
The open-source project V-CHONK by Rat Rig is aimed at passionate 3D printer hobbyists who want to assemble a space-saving yet powerful device themselves. The flexibility and modular design of this CoreXY desktop printer make it especially attractive for users who want to incorporate their own ideas in the design and customization of their printer. The project offers an impressive combination of efficiency, adaptability, and easy maintenance. This article will introduce the V-CHONK in detail, highlight its technical specifications, and show why it is an interesting option for the maker community.
Compact, modular design: A printer for small spaces
With a build volume of 180x180x180 mm, the V-CHONK is primarily aimed at users looking for a compact yet powerful printer. This print area may seem smaller at first glance compared to other models, but thanks to precise mechanics and thoughtful construction, it offers numerous advantages. Thanks to the space-saving design, the printer fits easily on any desk or in small workshops without sacrificing performance.
A key feature of the project is its modular design, which allows users to configure the electronics according to individual preferences. Users are free to either select and integrate electronic components themselves or use pre-configured bundles that are already optimally matched. This flexibility is a big plus for users who either already have experience with 3D printers or want to engage more intensively with the selection and use of hardware components.
3D printable parts and standard components
Another highlight of the V-CHONK is the high proportion of printable parts, which allow users to produce many of the components themselves. The project uses standard hardware, meaning many parts and tools needed to build the printer are easy to obtain and relatively inexpensive. This lowers the entry barriers for makers who want to build their first CoreXY 3D printer themselves significantly.
Precision and speed: The linear rail system
Technologically, the V-CHONK relies on a linear rail system that ensures precise movements of the print head. All three axes of the printer use MGN12C rails, known in the maker community for their accuracy and durability. These rails ensure the print head is guided smoothly and precisely, which plays an essential role especially in complex and detailed prints.
Lightweight print head and thoughtful gantry design
Special attention was paid to the construction of the lightweight print head and the gantry (bridge structure). These components are designed to keep the weight of the entire printing system as low as possible. This optimization allows high printing speeds without compromising print quality. Thus, the V-CHONK is also suitable for users who prefer fast prints or want to produce large quantities of printed objects in a short time.
The stable gantry construction significantly contributes to the overall performance of the printer. The solid yet lightweight design achieves a high level of accuracy, which is a great advantage especially for demanding projects. The modular design of the printer also allows parts like the print head or gantry to be adapted to individual needs.
Thoughtful cable management and maintenance-friendly design
One of the most common challenges with self-built 3D printers is cable management. Often, in complex constructions, it becomes an unclear task that increases maintenance effort and the risk of errors or failures. The V-CHONK cleverly solves this problem with a compact electronics area and integrated cable management. The cable routing is designed to keep the printer’s assembly tidy and organized. This not only facilitates assembly but also later maintenance and component replacement.
Electronics area and individually customizable equipment
Another plus of the V-CHONK is the compact electronics area, which despite its small size offers enough space to neatly store the necessary electronics. Users can decide which control boards, endstops, and sensors they want to use or rely on the electronics bundles suggested by Rat Rig. This flexibility makes the V-CHONK an ideal printer for tinkerers who want full control over their hardware.
The kit contains all essential parts needed to build the printer: frame, hardware for the kinematics, print bed, and a heating mat. However, the necessary cables are not included and must be purchased separately. This allows users to choose exactly the type of wiring that meets their individual requirements and avoids unnecessary electronic waste.
Self-production of parts: STL files and CAD model available for free
One of the most outstanding features of the V-CHONK project is that Rat Rig provides all CAD models, bills of materials, and STL files free of charge under the Creative Commons Attribution-ShareAlike 4.0 International License. This allows users not only to print the required parts themselves but also to customize and further develop the design according to their ideas. This openness promotes creativity within the 3D printing community and allows the printer to be continuously improved and adapted to new requirements.
Printed parts not included in the kit
It is important to note that the printed parts are not included in the kit. However, this is not a disadvantage but part of the concept that relies on the users’ initiative. By printing the parts themselves, users can ensure that these exactly meet their own requirements and can be modified as needed.
The provision of the STL files by Rat Rig also makes it possible to print the parts on an already existing 3D printer. Users can use different materials to optimize the durability and functionality of the parts. Additionally, if desired, they can use alternative designs from the community or incorporate their own improvements into the construction.
Community-driven development and support
A key feature of open-source projects is the possibility of community-driven development. Since all plans, CAD files, and information for the V-CHONK are publicly accessible, users worldwide can collaborate on the design and enrich it with their own ideas. This not only leads to a continuous improvement process but also offers the opportunity to share individual customizations with other users.
The Creative Commons license ensures that all developments and adaptations of the original plans also benefit the community. This creates a dynamic and innovative environment where creative solutions can be quickly implemented and tested.
Community support and knowledge exchange
Furthermore, users of the V-CHONK benefit from an active and helpful community. Thanks to the open-source nature of the project, there are numerous forums, groups, and platforms where users can exchange ideas and support each other. From tips for assembling the printer to discussions about specific optimizations – the knowledge exchange in the community is another advantage of this project.
Conclusion: The V-CHONK as an ideal project for 3D printing enthusiasts
The V-CHONK from Rat Rig is not only an excellent entry into the world of CoreXY 3D printing but also an exciting option for experienced users who value adaptability and initiative. The project impresses with its modular construction, use of standard components, and the possibility to print and customize many parts yourself. Despite its compactness, the V-CHONK remains powerful and precise.
The focus on community-driven development and open access to all construction data make the V-CHONK a particularly appealing project for tinkerers who want to realize their ideas and at the same time be part of an active community.
A printer for creative minds
Whether as a compact device for home use or as a basis for advanced experiments – the V-CHONK offers enough room for creative expression and individual design. The combination of precision, speed, and flexibility makes it a versatile tool for makers who want more than just an off-the-shelf finished printer.
