STEP file included to size to your preferred dimensions as this is designed specifically for 26mm timber that I had leftover from building a desk. As well as being sized in width specifically for my monitor. Length is determined by however long you cut your timber.
Highly recommend printing at a high layer height such as 0.28mm or more. This provides great strength over 0.20mm based on my tests. Model has a tiny 0.2mm chamfer on the bottom to help with first layer squish. Ensure the large chamfer is upright on the print bed.
The author remixed this model.
