I was looking for an airplane puzzle I could make both on my DIY CNC Router and print on my Robo 3D. I found this design of a generic Biplane. It wasn't until many hours (of recreating this airplane) later that I discovered someone had already uploaded a similar file. Note: This is not a remix of https://www.thingiverse.com/thing:2411381
After creating the initial layout, I took the liberty of modifying my sketched design to suit my liking. I also doubled-up the thickness of the main landing gear wheels to lend a better look.
Files are uploaded for the CNC,3D Printer, and Laser versions. For the CNC and Laser versions, remember to tweak the design for your material thickness and cutter diameter to get a nice fit.
There are no special requirements to print these parts.
For the 3D Printer version, I recommend letting the parts cool completely to avoid distortion. Parts slide together with little effort. As with any puzzle, there is a certain order to assemble the parts to build the plane.
For the CNC version, cut the parts loose from the their tabs, and sand as needed. Due to the size of the Wheel Retainers, that hold on the Wheels, there is no corner relief. You can either sand or file a square corner on each side of the retainers or chamfer the edges of wheel's inside diameter for clearance.
This was designed by tracing a PDF drawing of a Brazilian 3D Puzzle of a generic Biplane.
The initial layout work was done in AutoCAD. For a 3D view, I modeled this in Pro/E to create the STL files. I wanted to be able to 3D print this plane and cut it out on my CNC Router. The the Router files have all the cut-outs and corner reliefs defined for a 1/8" diameter bit.
The material for the wooden plane was purchased from Hobby Lobby and came in a package of three 10" diameter by 1/8" thick pieces of plywood.
