FMS Ranger 1220 Spinner (Snap On)

FMS Ranger 1220 Spinner (Snap-On Edition)

Upgrade your FMS Ranger 1220 with this redesigned, user-friendly propeller spinner. This version improves upon the previous design by offering a secure, reliable fit while remaining easy to install and remove.

Key Features

• Snap-On Design: No more searching for tiny screws! This model is engineered to click firmly onto the spinner base, providing a clean profile and tool-free assembly.
• Hex Nut Shaft Collar: Now includes a dedicated hex nut collar, making it significantly easier to fasten the spinner assembly securely to the propeller shaft.
• Support-Free Geometry: The model has been carefully optimized for 3D printing. It can be printed without supports, ensuring a clean surface finish inside and out while reducing post-processing time.

Propeller Compatibility

This spinner is designed to be versatile and works perfectly with:

• Stock FMS 10x5 Propeller
• uxcell/gemfan 10x5 Propeller: My personal preference for this aircraft. If you choose to use the uxcell/gemfan propeller, I have included two custom hole adapters in the files to ensure a perfect, centered fit on the shaft.

Printing Recommendations

This model is compatible with most 3D printable materials. For the best balance of weight and durability, I recommend printing with ASA, 

• Filament Choice: ASA PETG, or Tough PLA.
• Orientation: Print with spinner with the flat base on the build plate. Print the Hex Nut Shaft Collar with the hex side and the square corner flat on the build plate. Orienting the part this way ensures the layer lines provide the torsional stiffness required to tighten the propeller securely without the collar stripping or breaking.
