I modified a standard ZMR 250 frame by removing the aluminium spacers and the top plate and replacing them with a 3D printed spacer for a flat and sleek look. This also moves more mass closer to the center of rotation, improving the roll characteristics of the frame.
Available files:
- ZMR_250_Spacer: 15 mm high, no USB cutout
- ZMR_250_Spacer_USB: 15 mm high, USB cutout suitable for Betaflight F3 and similar designs
- ZMR 250 Slim Spacer v18.F3D: Fusion 360 Design File
Complete re-design 2019: Raw files available
Full redesign in Fusion 360!Several major improvements to the design:
- Fusion 360 design files available
- Fully parametric
- Quick edits possible through variables
- Fully symmetric design
Fusion 360 parametric design files
Autodesk Fusion 360 is a very complete CAD program which is now completely free for hobbyists.The design files for this spacer are now available for everybody to download and edit to their own preference. Full design history is available.
Parameter Modifications:
Through the quick edit parameters that I have set-up for you, you can now quickly edit:
- Overall spacer height
- Spacer wall thickness
- Diameter of screw holes
- Arm clearance to compensate for 3D printer accuracy
The raw design files include all raw sketches and images used to re-create the exact ZMR 250 frame geometry as best I could.
Fully symmetric design:
The design is now fully symmetric, no more offsets and being careful with part orientation.
