Pellet gun speed loader. This should hold approximately 20 .177 pellets for easy reloading of your single shot air gun. Simply slide the slider to dispense one pellet at a time.
This is a work in progress, I have not yet printed this because I am waiting to receive my TPU filament. The pen body should be printed in PLA or PETG, if you print it in a transparent filament you may be able to see the pellets in the pen telling you how many rounds you have left. The Pen Slider should be printed in ABS because of the flexible part that notches in the grooves. And the Rubber piece will be printed with TPU, I assume you could use a rubber band or something else flexible such as the rubber part of a ball point pen for this part. I intend to print it in TPU just to see if it works. The purpose of the rubber piece is to put pressure on the pellet retention clips. Like I said I haven't printed this so use at your own risk. I designed this in AutoCAD, and converted my .dwg to .dfx I can send source files upon request. I will update this once I have been able to print the entire pen and make revisions if necessary. I am open to feedback if you have any. Thanks and good luck.
