Extendable training cane

This is an extendable police baton designed for actual training of police units, however, it can also be used as a toy if flexible material is used.

Two different versions are included:

Long 190mm - 490mm and diameter 28mm.

Short 143mm - 390mm and diameter 28mm.

Can be used with real police baton holsters and the baton's folding and unfolding feel is the same as police unit batons.

The versions shown are made of TPU60D material which I recommend for any function without risk of breaking the product and without harming people, however, if your idea is to train techniques for apprehending and driving criminals, you may need to print it with rigid material such as NylonCF or insert a 6mm or 7mm rigid rod inside.

It has been printed with both rigid and flexible materials successfully, although because of its dimensions, I don't recommend it if you don't have some previous experience with 3D printing. In any case, if you don't have much experience and want to print it, I recommend you start with the short version.

There are optional parts, which change the look of the cane or protect the hand.

1-Due to its dimensions, it is necessary that you take adequate adhesion measures for this type of printing.

2-Supports are not necessary on any part, except for the sphere (8) and the cover (1), which will depend on what you consider.

3-You should use retraction to avoid threads because if you have threads, you will have to be very precise in removing them for the proper functioning of the product.

4-Use only walls.

5-Because of the characteristics of the product, depending on the flexibility, viscosity, distance of the nozzle between layers, etc. in the upper layers you can get less polished results. If you are experienced with 3D printing, you will have flawless results, for this reason I recommend starting with the short version if you are inexperienced.

6-The part (7A) is thinner than the part (7B), this is so you can use the most convenient part according to the hardness of the material you use.

7-Parts (2, 7A, 7B) should ALWAYS be printed with flexible material, the rest of the parts may or may not be flexible.

8-I have been informed of some problem fitting the trim piece, (3L, 3S, etc.) If you have some dimensional error in the print and no tolerance in the material, it may not fit, in such case, very slightly undercut the piece (4L, 4S, etc.) with sandpaper. I recommend using TPU for the trim pieces (3L, 3S, etc.) to ensure success the first time.
