P90 gel blaster

grabcad

This is a modified version of an original file called "Airsoft P90" made by Tomáš Němec (Airsoft P90).It was modified in such a way it is now ready to be 3D printed.However it is not an airsoft gun, it is a gel blaster based on Bingfeng P90.About the firing specs, it has a range of 25 meters with hopup and the stock spring. Good for CQB, not that great for outside games. I also added a modified version of a "Laser & Tactical Rail Mounting Bracket" and "Tactical Flashlight & Mounting Ring", both made by Andy Williams (Laser & Tactical Rail Mounting Bracket and Tactical Flashlight & Mounting Ring).The model also contains a stand based on a design of "P90 AIRSOFT STAND" by gumo_design, which is under CC-BY license (https://www.thingiverse.com/thing:2773868). A lot of additional hardware is required in order to assemble the toy. For instance, various sizes of M3 and M4 bolts, nuts and washers are required, M3 standoffs, M3 worm screws, various springs. I used springs which I gathered over the years, so you probably need to alter the dimensions where the springs are required. That is: mag release springs, fire mode selector spring, charging handle spring, trigger spring, upper retainer springs.Model was cut so it can be printed on any printer with dimensions of at least 225x225x225mm. However if a printer with smaller volume is used, the model can be cutted in smaller pieces and then glued with superglue or epoxy glue - in fact it is required to glue some parts anyways, namely the main body of the lower receiver (front and rear part of both halves).Also because this is based on Bingfeng P90, you will need Bingfeng P90 gearbox, T-piece, magazine and 9,5mm OD barrel.In order to work it requires a lot of soldering. There is an attached schematic with all the components needed. Due to the limited internal space, you need to make everything as small as possible. It is controlled by an Arduino Nano, the code is also contained in the design. Please note that originally it used a switch placed inside of the gearbox that was pressed when the blaster fired. But after some time it broke so I edited the code in a way it is no longer required. Now it is time-based (which means it is also voltage-dependant, as firing one shot with a fully-charged battery takes less time than firing one shot with nearly discharged battery, resulting sometimes in two shot burst in semi mode ...
