Hunting Bow - Inner Tube Self-Locking Stabilizer

Thanks to the "Yituo Wànjīnyóu"大佬 for developing the hunting bow launcher, this project is based on the latest "Malou version" long (400) hunting bow design optimized inner tube fixing accessories

Design Intent

The original project uses machine screws to fix the inner tube, which will scratch the inner tube, and because there is no stabilizing device at the far end of the inner tube, the movement of the inner tube may cause the trajectory to deviate

It is recommended to use machine screws + self-locking stabilizer together, or you can omit the machine screws and only use the inner tube stabilizer

Fixed using the screw holes reserved in the front section of the Malou version

Bill of Materials

2 hot melt nuts 3*3*5

2 countersunk screws m3*8

Precautions

1. Due to a large number of overhangs during the printing of the threads, it may cause the assembly to be too tight, please adjust the file scaling yourself; if the locking sleeve is difficult to install, some grease can be added to the threads
2. Different materials have different shrinkage, you need to adjust the model scaling yourself to adapt to different printers and printing materials, it is recommended to use PETG printing, PLA is easy to fatigue, the thread may be broken
3. Based on the 400 long version design, it has not been tested whether it is compatible with the 450 extended version
4. Does not support short versions
5. Due to the short exposed part of the hunting bow inner tube and the original screw holes are relatively forward, after installing the stabilizer, it may not be possible to install accessories such as bearing tubes. If you need to install bearing tubes, please test it yourself

Updates

Some designs have been optimized to make installation easier
