Playmat Tube - The Boring Aura

Just a boring and plain playmat tube, but easy to print and comes in a few configurations.  This is sized for a  standard 24 × 14" playmat.

Pick a split for whatever reason you like:

- Colour: every piece is its own part, so a 6-piece tube can be six colours. Stripe it, do a gradient, or match your deck's colours.

- Small printers: the 6-piece pieces are only 73 mm tall.

- Fewer seams: the 2-piece is just a body and a cap.

The pieces join with a twist lock: push together, and turn.  It clicks home with the pieces lined up.  Should withstand some light shaking, but it comes apart easily by hand.

The wall is a thin 2 mm. It thickens only in a band round each joint, where the lock needs the material, with a 45° taper each side, and the end edges are chamfered. That keeps it light, and every piece prints without supports.

- Inside: 56 mm bore, 365 mm long. That takes a standard rolled 24 × 14" playmat comfortably.

- Closed: about 370 mm long, whichever split you print.

- Footprint: every piece needs about 70 mm square of bed.

I've printed these tubes on a Creality K2 Plus and a Creality Hi, .4 nozzle at .2 layer height.  2mm for the walls , brim or no brim depends on how good your plate adhesion is.

- Order: the middles are numbered from the body up middle-1, middle-2, …), which helps when planning a color order.

## Assembly

Stack the pieces in order: body, middles, cap. To lock each joint:

1. Line the lugs on the lower piece up with the slots inside the upper one.

2. Push the upper piece down.

3. Turn it clockwise about a sixth of a turn until it clicks and stops.

To open, turn anticlockwise and lift.

I've added the stl files for a 3 piece tube so it can be previewed and zip files for the 2, 3, 4, 5 and 6 piece versions should be in the other files section.
