Designed to print without supports, and the included 3mf file is set up for a multi(two)-color print (printed on a bambu p1s). Four insets on the bottom of the restraining bolt allow up to four 15mm x 3mm magnets to be press-fit into place (no glue required). Two magnets is plenty, but Four will give a really strong holding force.
The author marked this model as their own original creation.
