(or any other cabinet)

Requires the following parts:

Mounting:
2x M3*10mm countersunk bolt (the longer the bolt the easier the mounting will be)
2x M3 hex nut
2x M3 washer

Assembly:
2x M3*6mm bolt (non countersunk)
1x Spring Ø~5mmx27mm (any ballpen spring should work)
Any type of thick grease

When assembling make sure to put grease on the moving parts, else the parts will tend to seize.
Ramp is glued onto the drawer to help close the latch without pressing it in.
