Ikea Lack Filament Guide Funnel

Why:
To allow free movement of Filament with no binding when going through an Ikea Lack Table top.
This design accounts for both the travel of the hotend as well as the change in where the filament leaves the spool.

Files:
Filament Guide. The Guide itself.
Filament Guide Hole Template to provide a template for cutting the top hole in the Ikea Lack table.

See Post Print instructions on how to use the guide.

Because of the fillets on the top I used a first layer raft so the print would stick to the bed better.

If your printer is in an enclosed chamber you may not have to raft.
If you don't have a water soluble raft. Then you may have to sand. I did.

a. Use the Guide to determine where the top hole will be in the table.
I used the original holes for the three "button" guides to help placement.

b. Ponder: "Do I really want to cut a hole in the top of the table?"
Think about how much less your extruder will have to fight the filament.
This leads to better prints.

Answer: Yes, of course you do. Proceed with the next steps.

Acquire the following

• A Jig Saw with a fine tooth blade
• A drill
• Vacuum Cleaner
• Masking or Blue Painters Tape
• A felt tip marker and a pencil.
• A piece or two of cardboard for tracing patterns.
• Protective Gear Recommended - Eye Protection, Dust Mask (The laminate is nasty stuff)

Do this first with cardboard then on the table, The cardboard allows for a test fit without cutting into the table. Do the test fit first.
a. Use Masking Tape around where the hole will be.
b. Trace around the guide with the felt tip pen.
c. Cut the test cardboard and check the fit.
d. If everything fit well, cut the table top with the jig saw.

a. Trace around the INSIDE of the guide with a pencil on the table bottom. Make sure everything lines up.
b. Drill a small hole at each end.
c. Check alignment.
d. Using something in the holes to provide a guide. (Example: Nail, bamboo skewer, screw)
e. Trace the small end of the funnel on cardboard. The cardboard will be used as the test pattern before cutting into the table.
f. Cut the cardboard out for a template.
e. Test fit over the bottom of the funnel.
g. Place the template over the guide in holes in the bottom of the table.
h. Trace the hole to cut.
i. Remove whatever is in the guide holes.
j. Using the proper size drill bit cut out the ends of the slot.
k. Cut the slot with a jigsaw..
Note: If you eyeball the slot instead of making the template you can end-up without a perfect slot. See image below.

1. If you rafted you may need to sand the top edges of the funnel. I did.
2. The funnel is a press fit. Feel free to glue or screw in place if you want or need to.
3. I plugged the old holes using a 9mm plug from here: http://www.thingiverse.com/thing:2214199

Other recommendations:
The laminate is kinda nasty stuff.

1. Vacuum up all the sawdust and bits.
2. Take a shower to get the dust off of you.
