A sturdy scale wheel chock set for medium size model aircraft, including two different base plates, designed to stabilize the aircraft’s wheels during transportation and at the field. The components can all be easily 3D printed, without any support, on a modern inexpensive 3D Printer.
These objects can be printed with a variety of materials, including PLA, PETG, ABS and other type of printable materials.
PLA works very well for this application. It is easy to print. The wheel chocks parts should be durable, easy to maintain, and last for a long time. However, they should not be stored or kept at high temperature, exceeding ~55 C (~ 130 F).
Should the wheel chocks components be left in a high temperature environment, such as a parked car in the summer, I strongly recommend using another heat tolerant material, such as PETG or ABS to prevent warping.
I have successfully used these wheel chocks sets since 2018 to stabilize my .40 to .60 size models, both at the field and during transportation. They work well to prevent the model from rolling off a table.
* The model aircraft shown in the pictures is a 68 in., 8.8 lbs (~1.3 meter, 4Kg), Black Horse Wilga, courtesy of Jim Ogorek.
Recommended print settings with a .4 mm nozzle:
- Layer Hight: .150 ~.160 mm, depending on motors and gearing
- 3 perimeters or shells (1.2 ~ 1.5 mm)
- 8 bottom layers (1.2 ~ 1.3 mm)
- 8 top layers (1.2 ~ 1.3 mm)
- Infill 15%~20%, depending on infill type
Assembly:
Use approximately 45 cm (18 inch) of small diameter rope, i.e. 5mm (3/16 inch), that fits through the chock’s central hole to link two chocks together. Tie a knot of sufficient size on each end of the assembly to prevent the rope from sliding back through the hole. Simple figure 8 knots on each end works well for me.
gCode files
For your convenience, the pre-sliced gCode files used to test these objects in our lab, are available on request for the following two 3D printers: Original Prusa MK2s and FLSun QQ Delta.
Please note that every single 3D printer is different. Therefore, your own printer may require additional calibrating and/or tuning to use the provided code sucessfully. We do not make any claims whatsoever, as to its suitability for your use on your printer. If you chose to use the included code, please be aware that you do so at your own risk. We cannot be held liable or responsible for any errors and/or damages that may result from such use. In other words "Your mileage may vary!"
