Cubbies in the PAC Closet Library are built in Mozaik as a low-fastener assembly: a fixed shelf defines the cubby zone, vertical multi-splits create the partitions, and a final multi-split inside each bay adds adjustable shelves that sit on the library's line-bored shelf-pin holes. Because the shelves are adjustable (not fixed), there are no dados or cam adjusters — it goes together fast and the homeowner can still re-position shelves later.
How do you build cubbies in the PAC Closet Library?
Phill Anton's method, step by step, working inside a closet section in Mozaik:
- Open the section. Double-click the section you want the cubbies in.
- Clear room for the cubbies. Delete the existing shelves where the cubbies will go to make room for the fixed shelf.
- Add the fixed shelf. Click the opening, choose horizontal split, and place a fixed shelf to set the boundary of the cubby zone (about 10 inches up in the demo).
- Multi-split for the partitions. Use multi-split (vertical) to create the vertical partitions in one move — this is the key to the method.
- Multi-split for the shelves. Inside the bays, multi-split again to add the adjustable shelves. Place them anywhere you like, because they ride on line-bored shelf-pin holes.
- Check it in 3D to confirm nothing broke before saving.
Why does this method use so few fasteners?
The cubby shelves are adjustable shelves on shelf-pin holes, not fixed shelves. The PAC Closet Library ships with the line-bored shelf-pin holes already drilled (a 5 mm hole in the underside of each shelf), so the shelves simply rest on pins — no dados and no cam adjusters. Fewer fasteners, less fuss, faster assembly. The partitions still get outriggers (nailers) at their tops and bottoms, which is normal.
What shelf-pin hardware should the cubbies use?
The library defaults to a comfortable consumer shelf pin — the K-line pin — set under Settings → Miscellaneous. If your job already uses the Q-PEG pin (the Titus-equivalent), that works fine too, because the pin holes are even and symmetrical. A Titus 6 fastener could technically work, but it isn't as comfortable for the homeowner to adjust.
How do you control which side the partition outrigger sits on?
Two tricks from the demo: switching a split to a divider flips which side the outrigger lands on; and for full control you can edit the "PAC Outrigger Nailers Partitions V2" fastener group (Libraries & Hardware → Joint Fasteners) and set the male-to-reverse on the into-fixed-shelf entry. This last step is a bonus — only if you're picky about which side each outrigger sits on.

FAQ
What's the easiest way to build cubbies in Mozaik?
In the PAC Closet Library, place a fixed shelf to define the cubby zone, then use the multi-split (vertical) command to drop in the partitions, and multi-split again inside each bay for the adjustable shelves. Because the shelves are line-bored adjustable shelves, you barely use any fasteners and assembly is fast.
Are PAC Closet Library cubby shelves fixed or adjustable?
They are adjustable shelves on shelf-pin holes, not fixed shelves. PAC's method uses the line-bored shelf-pin holes that ship with the library, so you don't need dado joints or cam adjusters.
