EDIT 6. April 2021:
I uploaded repaired stl file:
1_top.stl.
There was small coaxial probem, inacuracy.

Original:
precise filament guide for IKEA LACK enclosure.
Filament is guided by double rolls on ball bearings.
Needed:
8x ball bearing 624ZZ or 624 2RS
8x countersunk M4x16 DIN 965
8x spring washer 4,1 mm DIN 127B
2x M5x50 DIN 912
2x nut M5 DIN 934

I do not like support, so I divided model for several parts, you can easily print without support. Material PETG.
for installation you need to cut 64 mm (2 1/2 " ) hole on top of the IKEA LACK table above middle path of filament.
