Cabinet-/Restroom-/Toilet-/Quick-Lock profile-cylinder for standardized (european) door locks with a PZ ( German = Profilzylinder = Profile cylinder) opening for locking-cylinders.
This measurment is for 40 mm wooden doors but should easily be used for aluminium/aluminum or other cabinets doors. The square is a little bigger than the common size (8mm) for indoor doors.
I got it working without supports but the surface will be smoother/better if you use cylindrical supports.
The hole beneath the lever is for the fixing screw (M5-Screw)
No need for the hole to be threaded but go on and have fun, should work as well ;-)
!!!DO NOT USE THIS ITEM OR 3D PRINTED PARTS FOR FIRE AND PANIC DOORS!!!
These doors and all their parts need specialized approvals and are also subjected to meet certain qualifications!
