New version of wrist guards.
This wrist guards will be useful for lovers of snowboarding, skateboarding, unicycles and other extreme sports.
It consists of parts made of TPU or other flexible material that make the protection comfortable to wear (orange in the photos) and plastic parts that protect your wrist and palm in case of falling (turquoise color).
The parts are easy to change if necessary. Choose the length of fasteners for yourself, take smaller ones if you ride without gloves and larger ones if you wear them. There are also two different bases for different sizes of hands (models are for the right hand, for the left one they need to be mirrored). For small base, fasteners marked 'little' are suitable. Since fasteners are now printed separately from the base, the parts can also be printed on small printers.
Since different printers have various precision, there are 5 options for the plastic part located on the back of the hand, they differ in pin sizes (from XXS to L, XXS for least accurate printers, L for more accurate). After the optimal size has been found and the part has been printed, it needs to be bent with a hair dryer in the area of two points so that it is approximately 15mm on a ruler set at a right angle (see photo above).
I believe that it is important to mark the type of plastic used on the parts for further recycling, so I made 3 different versions of the plastic parts - with PLA and PETG marks (partially posted in zip archives) and without marking. I myself have always used PLA+ from Sunlu and find it strong enough.
I tested this version of the wrist guard for 1+ year riding the EUC, during which time I had several falls at speeds up to 30 km/h and the guards worked well. However, it is not a certified protection and I can not guarantee that it will prevent impact damage in any situation. I do not recommend wearing it at temperatures below -10 degrees, at this temperature plastic becomes brittle. Also, the lower the temperature, the more effort you have to put in to close the fasteners.
