You can find the improved V2 of this printer here https://www.thingiverse.com/thing:3863140
A corexy printer designed with ease of assembly, use and maintenance in mind. All rods on the build can be easily removed without removing any of the parts that hold them from the frame.
I am continuously updating the parts lists below and the models of the parts as I try new parts and improve the existing ones.
The printer build uses 2020 extrusions to keep the cost of low, while building a solid printer.
The current plan is for a 300x300x300mm build volume. You could use any parts you want to adjust the volume, however any bigger than 400x400x400 is not advised due to the parts designed for 2020 extrusions.
Using 2020 extrusions is a requirement, otherwise the parts will not fit!!
A list of all the parts needed to complete the build will be provided shortly after the full build is ready and tested.
Plastic Parts to print:
2 x Z Motor Mounts
8 x Z Rod Holders (pick the right version for 8mm or 10mm rods)
