Model 1377 Crosman air pistol pump piston

This is a cost-effective alternative to paying $3.00 plus shipping for a simple rubber component.\r\nSince I discovered various beauty treatments on Thingiverse for the American Classic, but no rebuild parts that actually work, I decided it was time to make one part available to users of this machine.\r\n\r\nI designed and created this replacement using an original part as reference. It fits perfectly in my 1377 and should do the same in yours at a fraction of the cost of the OEM part. The NinjaFlex material used weighs less than 2 grams, making it extremely lightweight. If you don't want to buy a whole roll of NinjaFlex just for this part, look for a sample - you'll get many pistons from that with a significant cost reduction.\r\n\r\nI print it with the cone facing down and only one narrow support in the center of the cone.
