Printable I3 base

thingiverse

Now SAFETY confirmed! Since the success of my current 3D printable Y carriage design, I have been asked to modify it for an i3. This carriage is based on the design and style of my highly successful carriage. The first design survived three re-designs of my 3D printer and about two years of use. Sagging due to radiant heat was what eventually led to its obsolescence. As such, I improved on the design, and I am happy to announce that it is now safe to use for ABS printing. ***Features*** The original design has been modified to accept the i3 Y mount and raised to fit into an i3's space. It has holes in the frame for zip ties to hold down the LMU88 bearings and the necessary attachments to stop the bearings from slipping. The part has now been updated to be 10mm thick, instead of the original 5mm thickness as bases were failing over long use. You can now use three-point stabilization, and it also has a mount for cable chains. ***Requirements*** It will require 16x25mm M3 screws and nuts to attach the legs to the body, washers are recommended. Also, three or four 50mm M3 screws with nuts, washers, and springs to keep the heated bed off the base. A sheet of cardboard and an air gap between the heater and the carriage is essential as it will protect the carriage from the heat radiating from the heated bed. And as with all parts for your 3D printer, ABS is the recommended material to construct this part. You will need two pairs of legs and one body to every base. Bearing mounts are optional. PS I have since moved on from using a plastic bed carriage and I don't plan on further development of this project. As it may help those on a shoestring budget get their first printer up and running, I'll keep this part posted and available for those interested in experimenting.
