Hotkoin's Oyumi Bungee Blaster

Created as a mix of those two designs by the talented u/Hotkoin;

First model
Second model

This is supposed to be a single-shot, crossbow-action foam blaster. It's meant to use 3/16 bungee cords as the propulsion mechanism but other types of elastic bands might also work with some changes.

--- CURRENT VERSION 1.0 ---

This has been printed and most kinks worked out. Current version should be reliable enough and simple enough to print and assemble to call it done. Fires around 50-75 FPS depending on ammo type and band used. It does prefer reasonable string tension and newer/stiffer darts.

Changelog from V0.2 to 1.0 ;

• Added a flat to the sled for better notching and dart impingment, made the sides round for best stylistic fit.

• Changed the nut to hold the sled closer to the darts and have less surface to move out of the way.

• Made the lower receiver channel guide channel ribbed for less friction on darts

• Adjusted holding channel from upper plates to hold darts better and closer to the nut and more consistent loading.

• Added notches to the front pegs so that string stays in place when firing, widened the channel for less friction.

• Adjusted crosspin dimensions. They should now perfectly snap in place.
