Simple Drawer Knob

thingiverse

I required drawer/door knobs for my printing station cabinet, so I designed one using FreeCAD as it doesn't necessitate support. However, the small screw hole might demand re-drilling. Please find the attached original FreeCAD file that is fully parametric, allowing you to edit it through a GUI rather than handling code like OpenSCAD. To modify the hole size, edit Sketch001 underneath the Pocket feature. For printing, I utilized ABS with 0.3mm layer thickness. The hole was supposed to be 3.2mm in diameter; however, it came out smaller. To rectify this, I redrilled it using a 9/64" drill bit (3.6mm) and used #8 wood screws (metric equivalent: 4mm). Although self-threading screws could be advantageous, they are not readily available at local hardware stores. Nonetheless, the wood screws functioned adequately for me.
