We didn’t design this model. It’s a community file from its original creator, and now and then a file has a fault that only shows up when we print it, such as walls that are too thin or parts that don’t join properly. If that happens we’ll let you know and try to fix the file, which can add a day or two. If we can’t get a good print from it, we’ll refund you in full.

Good to know before you order

TPU has a £11.50 print-order minimum. ABS, ASA, PC, Nylon and PETG-CF have a £46 minimum; PA-CF has a £69 minimum. Delivery is shown separately in your cart.

Please check the model files include everything you need before ordering. We print the files as published by the creator, so you receive the parts in the model, not necessarily a finished assembly shown in any photos. These are community designs by their original creators; we manufacture and post them but cannot guarantee fitment for your specific appliance or use case - check the original design page for compatibility.

About this print

A scale display model of the Wankel rotary engine, based on the 13B configuration found in the Mazda RX-7 and RX-8. The model represents the main internal components, including the rotor housing, rotor and eccentric shaft, with details drawn from the 13B-REW block. It is primarily intended as an educational or desk display piece for enthusiasts of rotary engine mechanics. PLA prints this type of detailed mechanical display model well and is widely available in suitable colours.

Original maker's notes

Based on exact size and dimensions of the previous remix, I added Added some more details and modifications to the rotor housing, rotor, and e-shaft(crank).

Housing: added an external casing based on 13B-REW block from 93-02 RX-7. Extended the spark plug holes from the origintal size so it reaches the outer edge of the outer housing. Exhaust holes on the side have different outer and inner ports.

Rotor: added round recess balls near the corners on top and bottom surface. Bulged out the outer arches to more accurately resemblance of the engine rotors while retaining the exact corner apex size and shape of the original model.

E-Shaft: extended the hex section to stack more layers of rotor housings and eccentric wheels. 13B shaft for 2 rotors, and 20B shaft for 3 rotors.

Housing Rod: Print 2x to stabilize the housings when stacked together. 13B for 2 rotors and 20B for 3 rotors.

the e-shaft(crank) and eccentric wheels are based on the latest remix by Aggressive. http://www.thingiverse.com/thing:129807

EDIT: Shortened the finger loop connector of the e-shaft(crank) so this model can still be spun while sitting on the table.

The Eccentric wheel has been re-created with the same dimensions as the previous re-mix to look more like the 13B engine with 3 circular holes. (had to alter the scale of these 3 holes from the real engine reference for stronger structural support)

Formatting may have been simplified. These are the independent maker's instructions and fitment claims; Hark Tech has not independently verified them.

Printing Remixed Wankel Rotary Engine 13B

For Remixed Wankel Rotary Engine 13B we would normally reach for PETG — it is tougher and more heat-resistant than PLA, ideal for parts that take load or live somewhere warm. We set the layer height, wall count, infill and supports to suit the model and how you will use it, and those choices are already priced into your instant quote. Want a specific colour or material? Tell us and we will match it where we can.
