I broke the rocker toggle on my favourite folding saw. Couldn't find it easily so I just modelled my own.
Print with supports flat side to the bed (open side up). I recommend PLA+ or PETG. The only weak point is where the spring sits, and I suspect it might be stronger if you print it on an angle. Mine has held up just fine and I flick the blade out so it's holding up to the abuse (I use it nearly daily for the past 4 weeks).
Printed:
Layer Height: .2mm
Supports: On
Filament: Matter3D Performance Black
