Alberto's Spool Holder

myminifactory

This design enables a portion of the weight to be distributed as an upward force on the piece of wood closer to the wall. The weight of all other spool holders should prevent the lever from pulling up that piece of wood. The lever is thinner than the body, allowing it to easily pass inside the space between a spool and the rack, even with a full spool. To prevent movement from left to right, the body (holding onto the front) is wider, preventing torque from the use of the spool hanging that makes the holder wobble. However, it is thin enough to fit between the walls of a spool without upsetting the rack. The only issue I can think of is friction on the spool that prevents it from unravelling for the printer. The edges that would be touching the spool have been rounded to prevent this, but it will really depend on the material this is printed with. In any case, enough space has been left on the top of the holder to place some bearings if needed. Thanks!
