Parametric clamping blocks with stairs for CNC

thingiverse

Parametric OpenSCAD model included for your customization pleasure! You can adjust the following parameters (default value in brackets): * Step height and depth [4mm x 2.666mm] * Number of steps for the stairs [15] and leg [3] * Step angle [30 degrees] * Thickness [20mm] * Hole diameter [8.5mm] * Hole length [25mm] * Leg length [70mm] * Leg's tail thickness [40%] Get started by placing the leg as horizontal as possible - only the tip will make contact, thanks to the half cylinder. Next, position the screw as close as you can to the part it will be attaching. Printer Settings: Printer: Kossel Delta Print settings: Rafts: No Supports: No Resolution: 0.3mm per layer Infill: 20% Notes: After several attempts, I found success with a step size of 4mm x 2.66mm. Trying half-step sizes resulted in inadequate grip due to my printer's average quality. To simplify things, the OpenSCAD model now defaults to these values.
