We have a Delta 3D printer at our shop lemnio.es without a spool filament, so every now and then the filament would break and the printing will stop. Also the motor was not able to pull the filament.

So we decided to make a simple spool filament holder made from recycled pallet.

Step 1: What You Need

We decided to make something simple, that will just hold the filament. We will need a piece of a pallet or some similar parts. In the image you can observe the dimensions, you can adjust them as you want.

Wood parts needed:

One pallet from which cut 2 pieces of 25cm long and one block
A circular stick, 20cm long and at least 2cm diameter

Tools needed:

White glue
8 x Screws
Electrical screwdriver
Jigsaw tool
Hand saw
Sandpaper
Wood sealer (optional)

Step 2: Cut the Parts

First we cut two pieces of 25cm long from the pallet. Using a regular hand saw. Try to cut 2 symmetrical pieces. If you are using a pallet, remove one of the blocks, we'll use it for the base of the support.

Then cut the stick that will hold the filament. 20cm should be fine. You can also use a miter saw.

Step 3: Cut the Holes in the Walls

Now, you have to mark the middle of the walls and mark a circle of the diameter of your stick. It's important for the circles to be centered in both parts, so the filament will stay right.

Using the jigsaw tool, cut straight until reaching the middle of the circle, and then move the piece so that you can cut in curve, along the circle mark. Test that the sticks fit. If it doesn't, just cut a little more or if you have pacience, use sandpaper

Step 4: Stick Together the Parts

We used white glue to stick the parts together, and then 4 screws in each side to hold together the pieces strong until the glue dries.

Be careful to clean all the remaining glue

Step 5: Finish

Use some sandpaper to remove any wood splinters or imperfections. At this point, you should check the support stays straight on the table. If it does not, sand it until it does ;)

We engraved our logo with a CNC laser machine, but I suppose this step it's optional.

Finally, we used some wood sealer to make the wood stand longer. You should wait for some 24 hours or whatever specifies the product in the instructions

Now the filaments keeps rolling and is easy to replace.
