Parametric spacer for building circular brick wall

prusaprinters

<p>This parametric script calculate brick spacing when building circular walls. A small spacing error accumulates quickly along distance around the circle. On a 50 brick wall, a 1 mm error builds up to 50 mm error.</p><p>Measure your bricks to find statistics and then use the maximum brick size. Using the mean value did not work for me, as the bricks vary in thickness &nbsp;along the edges and a few measurements to capture the mean value is not sufficient.</p><p>The spacer is relatively short to only adjust the outer spacing. Inner spacing must be done by aligning the brick towards the centre of the circle.</p><p>The cadquery scrip allows recalculation according to brick size, the number of bricks, and the diameter of the circular wall.&nbsp;</p>
