Tiertime UP Box/Afinia H800 Extruder Lock

thingiverse

This is a small part which mounts onto the print head carriage assembly of the Tiertime UP Box/Afinia H800, to secure the extruder assembly to the head carriage preventing movement of the extruder assembly while printing. This design makes use of the existing threaded M4 hole on the left side of the extruder heatsink left there from use with Tiertimes older legacy UP Mini and Plus models, but present on the UP Box and probably all Tiertime printers as they reuse the same parts for each machine. Use super glue or two-part epoxy to glue this part on the left side of the head carriage once aligned with the extruder heatsink M4 threaded hole. I used an M4x12 bolt with a washer and spring washer to secure it in place. I modelled this because I noticed Tiertime added an extruder locking/securing screw mount between the print head and the head carriage. The usage of this prevents the head from moving around on the magnetic carriage assembly while printing removing the chance of strange artefacts appearing on prints.
