About this 3D model
To compensate for the thickness of the flexible buildplate, the Z-offset lever must be fitted with a spacer. I have created several thicknesses, 1.5mm, 2.0mm, 2.5mm, 3.0mm. I myself use a 2.0mm spacer for the KOYEFEI flexible buildplate, which can still be attached with the original screws. For 2.5mm and 3.0mm I recommend longer M3 screws. Print the print file with 100% infill or with a sufficient number of top or bottom layers so that the spacer does not press in too much when the screws are tightened. Use at your own risk.
