Filament Reel - Tea Holder

If you use a 3D printer you will eventually end up with an empty filament reel, this can either be sent to the recycler or reused for some other purpose.

In this case I reused a filament reel as a tea holder although it could be used to hold a variety of other small items.

M2.5 x 12mm machine or Allen screws - Qty 5

M2.5 Plain flat washers - Qty 5

Filament PLA (red, yellow and green)

Filament reel dimensions are:

Diameter: ~196mm

Central Hole: ~72mm

Inner Height: ~54mm

Inner Width: ~58mm

As measured to the nearest millimetre.

Be aware that many different filament reel sizes exist and to check the sizes comform with these 3D elements, prior to printing.

May prove more cost effective to buy a range of values rather than individual values unless you already have them available. Some components may also have a MOL greater than the quantity specified in the component list.

Know your tools and follow the recommended operational procedures and be sure to wear the appropriate PPE.

No affiliation to any of the suppliers used in this project, feel free to use your preferred suppliers and substitute the elements were appropriate to your own preference or subject to supply.

The 3D printed elements for the tea holder were designed using BlocksCAD and consists of the following:

1: Base

2: Bottom

3: Lid

4: Draw (The radial draw for which 5 are required).

These create a 6 compartment (5 radial draws and a central container), tea holder with storage for ~35 tea bags*; made from a empty filament reel. However, the central container could be used to hold dry sweeteners or alternatively loose tea which would reduce the storage capacity to ~25 bags* 

*Tea bag quantities are based on neat layered storage for round bags of ~68mm in diameter, although these could equally be square. More or less could be stored based on the size and the degree of compression, although too many bags could compromise opening and/or closing of the draws/container.

The elements of the tea holder are printed in PLA using three colours (red, yellow and green).

For longterm use utilise certified compliant food safe materials and practices regarding the filament, nozzle, bed and application of surface coatings etc.

The elements in the files are orientated as they will be printed. 

The radial draws are in the shape of a pie segment from a hollow cylinder.

With a vertically orientated half cylinder handle and with a slot in the bottom into which a M2.5 x 12mm machine screw with compatible washer is fitted to retain the draw in place when fully opened.

Size: 113.5 x 76.3 x 53 mm

Weight: 24g

Print Time: ~3hrs per draw.

No supports.

The central compartment consists of two circular parts (a bottom and a lid), both with an interference fit to hold them in place and a lip to prevent over insertion.

The lid contains finger inserts to enable insertion and extraction.

Bottom.

The base consists of a ring on which the completed unit sits. This has five holes into which the retaining screws for the draws are fitted. Securing both the draws and the ring in place.

Base Adhesion: Skirt

No supports.

Some sanding may be required to remove surface aberrations particularly with regard to the inner surfaces of the bottom and lid.

The container bottom is inserted into the centre of the reel and simply pushed into place.

The same applies to the lid.

Regarding the draws.

Align the base ring, centrally on the designated side of the reel which will sit face down and tape in place.

With a 2mm drill bit make 5 holes using the base ring as a template.

Pass the washer over the screw and the screw through the slot in the draw with the head on the inside. Tighten the screw such that is passes through the side of the reel and through the hole in the base ring. Repeat the process for the other four draws.

Fill the draws with your favoured tea or teas and the central compartment as suites your requirements.

Be sure not to fill the radial draws with loose items that can fit througfh the slot in the draws to prevent the contents escaping or jamming the draw.
