I’m trying to make some 3D-printed guides to help me tap some of the extrusions. It would be great if the Mk2 CAD could be released, as the extrusions in MK1 do not seem to match MK2. (Or, Mk1 CAD is wrong) ![image](https://forum.sienci.com/uploads/default/original/2X/8/8800ecd13ef1ddfd484d09126bd5ac4415a133e4.png) ---

Here is the [LongMill Mk2 Onshape page](https://cad.onshape.com/documents/59335d21bb649cd2b941a693/w/290c65d1d584435649b87e46/e/99a028de0f32d790196bbe8a). And yes the Mk1 rails are just 90 degree aluminum. FYI, most of the Resource pages have an Open Source page in the Advanced section where you can usually find links to the CAD files. ---

Oops, I get confused with all these new products. I can’t believe the AltMill is already on the second version. It feels like it just came out. 😕 ---

@greg5 This has been requested multiple times. Another user posted here a few weeks ago and he was told that the OnShape cad drawings aren’t clean enough to post publically yet. They did send him the drawing of the crossrail profile though. ---
