Carbon-Fiber Handle for Printrbot Simple (update)

pinshape

The Printrbot Simple is a compact 3D printer that's easy to transport, as long as you have something sturdy to hold onto. The latest models come equipped with a handle, which meets the original requirement. The carbon-fiber handle parts were among the first items I printed after getting my Simple up and running. This handle can also be made from an oak dowel, but the carbon-fiber tube is significantly stronger than wood and feels more secure when carrying the printer. The design has been updated since August 5, 2013, to fit the Beta Test version of the Simple. To assemble the Carbon-Fiber Handle, follow these steps: Print the handle parts in two groups to accommodate the size of the Simple printing bed. Cut three pieces from a 0.210-inch carbon-fiber tube: two 8.5-inch long and one 4.25-inch long. Attach two O-rings to each carbon-fiber tube. Insert the tubes into the printed parts. Drill 1/32-inch holes through the printed parts with tubes for pinning them in place using nails. Cut nails to 0.5 inches if necessary, then push them through the printed parts with pliers. Cover the nails with O-rings to keep them secure and complete the handle assembly. Locate the handle on the Printrbot Simple and drill holes for screws. Attach the handle with screws. Enjoy your newly assembled handle! Materials needed: Four printed parts Four O-rings (ID = 7/16 inch) Six #2 x 0.5-inch brass screws Six #19 x 0.5-inch wire nails (or cut longer nails) One 0.210-inch carbon-fiber tube from Amazon.com, cut into two 8.5-inch pieces and one 4.25-inch piece Note: Printed parts may split along the grain, but O-rings alleviate this concern. Confession: I printed my Carbon-Fiber Handle parts in ABS on my Printrbot LC to safely handle my Simple from the start.
