I loved this design and printed one up and then ran up to Lowes to buy a 3/4" x 8" board. To my surprise there are no actual 8" boards in Lowes. Anything advertised as 8" is in reality 7 1/4".

Hate to call this a remix as it is more like a resize of the x axis to 197.08 mm overall which fits the store bought 7 1/4" boards perfectly.

Printed with PETG with the following settings (as per the original source):

9 Perimeters 0 Top and Bottom Layers 5% infill
