1st place: Petforu Stirling Engine by Hussam Fraij
A Stirling engine is a heat engine that operates by cyclic compression and expansion of air or other gas at different temperatures, resulting in a net conversion of heat energy to mechanical work. Hussam was asked to reverse engineer the engine. He disassembled the components and precisely measure the parts using a digital Vernier caliper talking into account the geometrical dimensions and tolerances. He then modeled each part separately in SolidWorks before the assembly. He did simulation for the movement and rendered the assembly using Fusion 360. He generated engineering workshop drawings for each part and one for the assembly. Hussam is an industrial engineer with 18 years of experience in design and manufacture CAD/CAM/CNC.
2nd place: Multi-diameter Filament Head Concept 5 by David Byram
The MULTI-DIAMETER FILAMENT HEAD- CONCEPT5 was developed due to the issues involved in FDM 3Dprinting deposition size and speed. To date, most if not all filament printing systems use a single nozzle of desired size, usually small in the 0.4mm to 0.6mm range. That works well for fine printing however when printing support filament or filament merely to fill a void or create thicker wall cross sections, a larger diameter would increase the speed of the print. This design utilizes four different nozzle orifice sizes that are indexed into place using a control cable connected to a gear motor. When a different size nozzle is needed, the ho tend rotates in increments of 90 degrees. Only one filament feed tube is used. This concept is built around the 1.75mm filament stock size. David used SolidWorks in creating the design. He is retired but not from designing, he keeps his mind sharp with part time freelancing.

1st place: Edwards Radial Engine by Chris Dabek
Chris is no stranger to the 3DX Model Showdown, his models have earned him previous wins. This model engine was yet another challenge for Chris. He had to figure out how to adapt springs into the model and actually make them move along with the motion. He used 3D sketch paths for sweeps for the oil lines which is something he enjoyed doing in Inventor. A lot of the model was also modified from the original plans to reflect his unique touch.
2nd place: Snowboard Binding by Craig Steele
Craig's initial inspiration came from an old snowboard binding that he thought had a boring design. He jumped in and designed this binding in SolidDesigner. He says the refinement of the compound surfacing / proportions became quite challenging from the start. Having no straight edges anywhere on the main pad made it an uphill challenge but definitely worth the effort as he learned a handful of new tools and tricks to strengthen the overall structure of the model. The details of the buckles are actually one of his favorite parts of this design.
3rd place: Racing Drone by Ken Son
A long time SolidWorks & Catia user, Ken has been designing more and more in Fusion 360 as it becomes more mature.
Ken wanted to build a tiny "race" drone, but didn't want to spend a lot of money. He had parts left over from previous larger drone builds but those parts were oversized for the size of drone he wanted. So he decided to model everything up and figure out where to place everything before building the real thing. He took the pile of parts and painstakingly measured everything as exact as possible, drew up the components, and placed them in ideal locations. Once the parts were in place, he modelled and printed the little bits on his 3D printer to hold all the parts together.
