This is an extension for effect pedals with 10mm foot switches to increase their surface.
It is roughly based on this: https://www.thomann.de/de/mooer_candy_footswitch_topper.htm
It has a diameter of 24mm an a height of 12mm.
Examples are printed in orange Overture PETG but should work with other material, too.
It is important to put the internal Z-seam in one of the wider areas.
For a perfect fit i used +0.1 as XY Hole/Contour compensation.
First print plate contains a version with a band logo, the second printplate has one with smooth surfaces.
