Magnetic key used to conveniently eject filter sliders or blind filters from Astrodevice drawers. Simply move the key over the drawer and pull slightly.
The key is equipped with a hole so that you can hang it on a lanyard and have it with you all the time without worrying about where it is during your astrophotography session. However, if you do happen to misplace it, you can purchase a replacement here.
The base of the product are 3D printed elements made of PET-G CF filament (polyethylene terephthalate glycol-modified reinforced with carbon fiber).
