Dinky little toy blaster. it shoots about 30 feet, is pretty small and is made out of purely printed plastic and two rubber bands (One for the trigger and one for the magazine).
It requires no fasteners, or glue, and just uses printed tabs to connect the clam shell case.
It uses about 45 grams of filament, can be printed in PLA and has only one part that uses supports, (that are easy to remove and on the trigger).
The magazine clicks in and is pulled out the same way
It fires 6mm airsoft bbs

Printer:
Creality CR-6
Rafts:
No
Supports:
Yes - In one place only
Resolution:
0.2mm Layer Height, 0.4mm Nozzle
Infill:
15% (whatever you usually use is probably fine)
Kexcelled PLA K5 Green (but anything works (the more springy and stiff the pla the better for ball velocity)
Rubber band follows the path shown. Make sure to pull the trigger halfway or more so that the Bolstracikter (Thing that hits the bbs) is seated properly and inside its rail.
You'll want to clip the 1 layer thin bit of plastic on the follower to allow the band to go through. Next you get the band around the nub on the follower, and let it dangle through the magazine body. Third you get the band onto the bottom band point on the rear cover, then rotate it to get it to run over the top. Lastly you push it in with the clips holding it in place.
Designed using F360.
Created Tabs as one part with Male rough, Male, and Female tab components with make added to one side, female to the other, and the male rough used to cut out the female half. These were all the various prototypes made trying to arrive at the conclusion.... I need to get better at failing fast and frequently.

The rubber bands used
The rubber bands used for both the trigger and the magazine is pictured, though you can wrap a larger rubber band around twice for the trigger, or the magazine (this will be tricky so just using a smaller one is better than bigger)
I bought a pack of these labeled as 2.5cm: https://www.aliexpress.com/item/1005001872435921.html?
Those are used in both the blaster and the magazine.
I like 2 bands in the blaster to make it more springy.
