Silver bar
thingiverse
This is a straightforward project involving silver bars, with two files that feature concave and convex designs. Adding cavities for magnets poses no significant challenge, although it's understandable if you're feeling unenthusiastic; in such cases, simply set the infill to 10% and place your magnets during the printing process - my 3x8mm magnets fit snugly without any issues.
