The Drawn Line (Súng Nerf Pistol In 3D)

Hi! I designed this blaster over the course of several months and have made a decent product. I am still working on it so don't expect it to be perfect.

It was originally designed for proper hardware, but I realized that it can handle the forces if the hardware was 3D printed. Although it doesn't feel the greatest to prime when full printed, it is capable of handling more than 200 FPS with a small form factor. Expect up to 230 FPS with proper hardware. I imagine 240+ is possible.

Keep in mind that is is originally designed for full metal priming bars. Printed bars will always feel worse and will have flex. Its easiest to prime it when holding it as high up on the grip as possible and pulling parallel. Also I highly recommend PETG parts for the sled since it is less brittle than PLA and has a lower coefficient of friction.

I am still working on a metric version.

Parts wise, it could cost as low as $8.20 per unit, but there are a lot of individual parts. The spreadsheet goes over what parts are needed. You can probably buy almost everything from a hardware store to avoid buying parts in bulk.

Assembly Video (for release version 1):

For the highest FPS, I recommend 140mm Lynx springs from Out of Darts. Please give it a go! Tell me what you think!

I appreciate everyone who bought the original files, it really means a lot to me! Thank you for the support along this journey <3.
