This is a rework of the Fusebox 2020 by Culain, which in turn is a rework of the Original Fusebox by AlexY. However at this point, there's not really much left of the mechanical workings of the original design. All the Carriage parts now have push fit bearings opposed to being cable tied. The X and Y Axis have been re-designed from the ground up to allow push fitting of the bearings. The Z axis is still mostly Culain's design, but has been modified to allow push fitting of bearings.

The Ethos of the Fusebox was to keep parts pricing low, which at the beginning of this project, was the same aim, however, it is now to improve the FB2020 to a point where it's pretty much it's fool proof and highly reliable. I want it to the point where anyone with a set of Allen keys can put it together. I'm happy with the frame rigidity, yes, it's not as rigid as it could be, but I still want to try to keep costs down where possible, by using printed plastic parts this helps a little. I've added a list of upcoming changes below.

All files should be orientated correctly for printing. Any file marked Culain is an original file from Culain's design and no physical changes apart from mirroring and orientating correctly have been made.

There are 2 versions, the Standard FB2020 and the FB2020 Plus. The Standard has a build volume of 200x200x170 and the Plus has a Build volume of 200x200x275

####NOTE: All bolt, rod and hot end holes on the STLS for the Carriage and Carriers have a 0.4mm tolerance. If you need less or more, grab the SCAD files. There is a setting in there to change it.

####Further Plans

  • Overwork parts in FreeCAD format - in progress.
  • Change the Schlotzz extruder for an E3D Titan
  • Change the Z to use 10 or 12mm smooth rods - less z wobble - in progress - designs uploaded - waiting on parts
  • Look at the possibility of changing the push fit bearings to clamped - stiffness
  • Change out electronics for 24v - better heating - not urgent.
  • Assembly instructions
