In this work, B0-shimming techniques are investigated allowing the construction of simple, low-cost, and homogeneous Halbach-based low-field MR magnets. The techniques are applied to build a desktop MR magnet at B0=0.1T and can be easily scaled to magnet designs of larger diameter. The presented shimming approach improved B0 homogeneity by a factor of ~8 from 5448ppm to 682ppm in a 2D target region. All design files and code concerning this work will be made available open source on
