(no rubber band) FULLY PRINTABLE Otf Fidget Toy by LUN5HTIME:
OTF Fidget Knife by Patpatrouille:
------------------
In LUN5HTIME's OTF model, the ‘riser’ on the base of the blades that joined with the coil spring was too thin and fragile resulting in breakage.
In Patpatrouille's model the spring and trapezoid-blade combination fixed the issue of LUN5HTIME's fragile blade ‘riser'. However, Patpatrouille didn't have a a double-edged blade like LUN5HTIME so I remixed the best parts of both blades.
The result is the use of Patpatrouille's better coil spring with the use of both Patpatrouille's and LUN5HTIME's blades.
I found Patpatrouille's case lid difficult to assemble to the case base so I remixed parts of the lid features.
The result is a case that's easier to assemble and disassemble.
Thank you to both LUN5HTIME & Patpatrouille for their valuable contributions!
