Parametric remake of Hero Me Gen 5 Gantry Adapter 1 for Ender 3/CR-10 (with additional files for threaded inserts)

thingiverse

I had a limited supply of spare nuts, so I remade the gantry adapter 1 in OpenSCAD to use threaded inserts instead. The Gantry Adapters in this design are compatible with CR-10, CR-10S, CR-10S4, CR-10S5, CR-20, Ender 3, Ender 3 V2, Ender 3X, or Ender 3 Pro models. The **gantry_adapter_1.scad** file attempts to replicate the original **CR-Ender_OEM-MS_Gantry_Adapter_1A.stl** file from Hero Me Gen 5. It was compiled as **gantry_adapter_1a.stl** and is suitable for use with OEM, MK8, Creality 'V6 style', or Micro Swiss hotends. We also have other pre-parametrized files: - **gantry_adapter_1b.stl** attempts to replicate the original **CR-Ender_E3D_Gantry_Adapter_1B.stl** file from Hero Me Gen 5. It is designed for use with E3D V6, Volcano, TH3D Tough, Mosquito, or V6 clone hotends. Parameters: ```HAS_HOTEND_BLOCK = false;``` - **gantry_adapter_1b_threaded.stl** is a modification of **gantry_adapter_1b.stl** to use M3X3X4mm threaded inserts instead of nuts. Parameters: ```HAS_HOTEND_BLOCK = false; GANTRY_SCREW_R = 2.1; GANTRY_SCREW_R2 = 2.4; GANTRY_SCREW_HEIGHT = 4; PROBE_SCREW_R = 2.4; PROBE_SCREW_R2 = 2.1; PROBE_SCREW_HEIGHT = 4; PROBE_SCREW_FN = $fn;``` - **gantry_adapter_1a_threaded.stl** is a modification of **gantry_adapter_1a.stl** to use M3X3X4mm threaded inserts instead of nuts. Parameters: ```GANTRY_SCREW_R = 2.1; GANTRY_SCREW_R2 = 2.4; GANTRY_SCREW_HEIGHT = 4; PROBE_SCREW_R = 2.4; PROBE_SCREW_R2 = 2.1; PROBE_SCREW_HEIGHT = 4; PROBE_SCREW_FN = $fn; HOTEND_SCREW_R = 2.4; HOTEND_SCREW_R2 = 2.1;``` - Default parameters: ```HAS_HOTEND_BLOCK = false; GANTRY_SCREW_R = 1.651; GANTRY_SCREW_R2 = 3; GANTRY_SCREW_HEIGHT = 3.657; PROBE_SCREW_R = 1.843; PROBE_SCREW_R2 = 3.403; PROBE_SCREW_HEIGHT = 2.681; PROBE_SCREW_FN = 6; HOTEND_SCREW_R = 1.602; HOTEND_SCREW_R2 = 1.602;``` My threaded inserts are the affordable ones (https://pt.aliexpress.com/item/32842866575.html?spm=a2g0s.9042311.0.0.233eb90aSphDwA). You may need to adjust the parameters for your inserts. The photo in this design is a **gantry_adapter_1b_threaded.stl**. I printed it because my Ender 3 has an E3D V6 hotend. PS: Don't ask me about micrometer precision. I tried measuring from the original model and these are the values I obtained. Some dimensions may be off, but it doesn't seem to have any impact.
