Download and Print parts The part names are the same as the file names. If you want individual part files, please download them directly or the [Onshape Document](https://cad.onshape.com/documents/6be13b87a3aad01bd61ef6ab/w/86f8cbb4c7b89f36daabaded/e/60b90b400b488f7dba307a1d?renderMode=0\&uiState=6765edde24e35a5f7c804100). #### Plate STL Files for Printing

## 2. Check Tolerancing ### All Finger Joints The dowel holes may warp during printing, so check that the dowels can fit into the holes (do not push too hard as it may crack the 3D print). These outer dowel holes should fit the dowel loosely. The inner dowel holes should fit more snugly but not require much effort to press in. If the dowel does not fit, use a 2.5mm drill bit to drill out the holes. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://ruka.gitbook.io/instructions/hardware/3d-print-parts.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
