Milwaukee M12 battery holder and wall mount

thingiverse

This is a battery holder and wall mount for the Milwaukee M12 battery system. Available are several STLs - one and three battery versions can hold extended capacity batteries in all slots while the four battery version can only hold extended batteries in every other slot. Note that the three battery version is 218mm wide, and the four battery version is 224mm wide. On request, I can provide other STLs for 1-3 batteries with narrow or wide spacing (which accommodates the XC battery), or 4 batteries with narrow spacing only. Print Settings Printer: FlashForge Creator Pro (2016) Rafts: No Supports: No Resolution: 0.2mm Infill: 15% Notes: The sides and back walls are 2mm thick, meant to be solid. Set print width and number of perimeters for optimal results. For example, with a .4mm print head set print width to .5mm, use at least two perimeters. How I Designed This Designed in FreeCAD 0.16 I designed a rough model using the battery as reference. From there, it was tweaking and printing out tests until spacing and rotation were right. The CAD file has multiple cutout templates that were experimented with before uploading just two versions to Thingiverse. If you want other layouts, follow these steps in FreeCAD: Switch to part workbench If not visible already, open Combo View panel (View --> Panels --> Combo View). Select Model tab Delete last three steps (Chamfer, Fillet##, Cut). After deleting cut, select Battery object in Combo view and hit space bar to hide the cutout template. Double click BasePad, edit length to whatever number noted on battery cutout you want. This changes the object's length to fit your desired number of batteries. In Combo View, select TopEdgeFillet_LastBeforeCut, then CTRL-click on battery cutout you decided (continue example in last step). Apply a boolean cut. You should have a usable model with proper cutouts. Switch to Part Design workbench Select top face of object (where holes are) and apply fillet of 1.5mm. This smooths out the edges on top. Select any edge on bottom lip of battery holder hole(s), then apply chamfer of 1mm (for multiple batteries, CTRL-click). This helps smooth out the bottom edge of the hole. To export object as STL, select final object in Combo View, then go to File --> Export. The bottom chamfer isn't strictly necessary but may help if your bottom layers get squished or expanded.
