Template ID: rigid.magnetic.tray
Component: Rigid boxes
Current template version: V1
Dieline preview version: V1

This template is a component of a packaging assembly. Match its dimensions to the other parts; lids, bases, wraps and linings serve different purposes.

How it is assembled

Erect the grayboard at the grooves: front and back walls first, then position the end walls between them. Secure corners with corner tape, glue the magnet flush into the recess, then wrap.

Material and grain direction

Grain direction of greyboard and wrapping paper parallel to the x-axis of the blank: the long grooves fold cleanly, and board and paper do not warp against each other during wrapping (check with the rigid box manufacturer).

Test fit, folding and closure on a sample made from the intended material. Confirm material thickness, grain direction and production steps with your printer.

Compare opening and presentation: pillow shapes, bands, drawers or lift-off lids. Plan the fit of contents and inserts and allow clearance between moving parts.

What to consider for this construction

Joint gap

The walls placed between the long walls are shorter by this value at each joint so they do not bind during erection.

Magnetic closure

Round recess for a disc magnet in the front flap and the tray's front wall; wrap and lining cover the magnets.

Magnet diameter

Disc magnet diameter; the recess is 0.5 mm larger.

Magnet height

Height of the magnet center above the tray's bottom edge (outside); the assembly sets it to match the flap's magnet.

Frequently asked questions

What does the separate inside lining do?

The inside lining covers the case wrap's turn-ins and the magnet in the flap. It is smaller than the case all around; liningMargin starts at 3 mm. Its hinge lines follow the case. Check glue application and movement on the sample so the lining neither strains nor blocks the hinges when closing.

Which magnet size does the example show?

The individual part's starting value is a disc magnet with a 10 mm diameter. The model creates a 10.5-mm recess in the tray's front wall and flap. Diameter and position are construction values. A fitting opening determines neither magnet thickness within the material nor holding force or polarity. Confirm the magnet, flush installation, and adhesive with the rigid box manufacturer carrying out the work.

Why is the tray's magnet height initially 25 mm?

25 mm is the parameter default for the individually calculated tray template and belongs to the existing preview. The assembly overrides it to match the flap; in the starting case, with 22.8 mm. This distinction matters for assembly. Do not transfer independently calculated magnet positions into a finished assembly without checking their alignment.
