Airsoft p90 - m4 mag adapter

thingiverse

UPDATE!!! after testing, have increased the diameter of the tube inside so bbs can pass easier for better feed rate. use V3 also added pin for latch this is an adapter for a p90 mag to m4 mag. i am using a CYMA p90 but this is modelled off a standard p90 mid cap so should fit any. main body print time is around 13 hours. everything is 3d printed including spring for mag release, will need to be glued in place. also a pin is needed for mag lag. will add this but anything fits and works well...allen keys are great haha very specific settings for support are needed or it will not work. all details are in the picture support must be turned off for the overall model or it will print supports in the internal tube where bbs feed. there are 2 90 degree angles so you will never clear it. instructions in the pic for where to add support blocks to change settings a put supports on where needed. i printed this on a cr10 at 12% infill. feels strong and really good. where m4 mag chamber attaches i used a modifier in cura to up the infill to 25% to make sure it wont snap off. read instructions of usinngs bbs and silicone oil post print (in the picture) i will add a file where the mag is cut in half and has attachment pins to join and glue after print for anyone whose print bed is too small. mag must be joined correctly or it wont latch into the RIF correctly so it wont feed. model is likely upside down when importing to cura, just out flat side down, its obvious. spring will need supports and is then glued in place on the side of the magwell. there is a small square the flat side will fit into to keep in place whilst glue dries. test the latch works fine with the spring in before glueing (brim might make it hard to clean spring so it operates and fits perfect but it recommended as its a small part EDIT: added a mirrored version for left handed players
