The Thumb Saver speedloader attachment

After enduring a lot of pain trying to reload my airsoft mags by holding back the spring by using my thumb, i have designed a little finger to assist with reloading mags. To use the tool attach it to your speedloader (must be a 100 BB speedloader in pistol format) pull back the spring of the mag until there is enough room for the large finger to slide into the BB grove, and simpely pull back and dispence your BB's. I can only garantee a good fit on the ASG 100 BB speedloader, others might not fit.I reccomend printing it in the orientation provided and to print it out of PETG, this will guarantee the strongest part.
