Introduction: Knex Ball Machine Improved Hof: Even Smaller Than Before!
This is one of the smallest knex ball machines on instructables. I just took Leigo Andre's hof ball machine and took out some unnecessary pieces. The ball machine is not smaller than hof, but it uses less pieces. Sorry I don't have a video, but it works the same as hof. The only knex ball machine on instructables that uses less pieces is hof jr.
