The trigger on my VWR Spray Bottle was broken, so I printed this fix.

In order to install it, unmount the plastic cover, push the part in sockets and mount the cover back.

Supports are needed.

Notes:

I printed it with 0.15 mm layer height, but I guess bigger height would work as well. Used 15% infill for the whole part, but used a modifier to set 100% infill on mounting hooks.
