μPurge

I'm still refining the bucket design, so bear with me. The mounts and carriage are mostly done, but I'm not satisfied yet. Most multi-filament solutions have one major flaw: the purge block uses way too much material than necessary. Some printers allow you to move the head off the bed for purging filament, which won't work on delta printers. This design uses an OpenBuilds linear actuator (check out https://www.aliexpress.com/ite...) paired with a small gantry plate. The carriage attaches to the gantry plate and features a connector that holds the bucket itself in place. The version shown in the photo employs a silicone wiper, but I might swap it out for purging onto aluminum instead; the uploaded bucket STL is a slightly different design. Be sure to purchase an extrusion separately, as the linked actuator doesn't come with one.
