This frame is compatible with the original Technic parts and it should fit with the standard Technic pins.

For optimal results, make sure to:

• Use low layer heights (~0.12-0.15mm)
• Use high cooling settings (depending on filament, up to 100%)
• Select slower printing speeds for maximum details

or use the given print profile.

Supports aren't necessary if printed lying. With a smaller nozzle diameter you can achieve even more accurate results (max. diameter should be 0.4mm). If the holes are too small and the axles have too much friction, try to rotate them inside the holes to enlarge them a little. If the results are just too inaccurate, check your print settings or use a smaller nozzle diameter.

Feel free to upload a better remix version or leave a suggestion for improvement

Have fun :)
