I improved my own version of the filament guide for the IKEA Lack table.
NOTE: All parts (V1, V2, V3 are compatible between each other. It is your choice which one to take.
This one has two rolls to guide the filament sideways. This prevents the filament from getting stuck at the end of the filament guide (particularly while printing large objects at a certain height).
This one is for 1.75 mm and also 3.00 mm filament at the time. Let me know if you need other diameters, then I will build them for you. There is also 1 version to add a 4 mm PTFE Tube now!
Instructions:
- PRINT THE PARTS AS THEY ARE ORIENTATED IN STL-FILES!
- First stick the filament guide into a hole in the table (drill 10 mm diameter hole in the table top)
- Then add the "nut" (make sure the larger ends point left and right! If not, losen the nut, turn the filament guide a bit and then tighten the nut again)
- Place the two rolls on the 608-bearings
- Stick the two 608-bearing onto the plate and place the plate on the nuts
- Screw the plate onto the nut. You can use any screws that will fit through the hole.I use plastic-screws, but you can also drill bigger holes and take metric screws for example. If you want be to design this for metric srews, let me know in the comments.
Changelog:
2017-10-13: >>> V2 is here! <<<
- rolls thickened
- the plate has two more srews to better stick to the nut
- the chamfer on top of the nut‘s two pins was too big, it got thinner
2017-12-10
- Added filament guide for 3 mm diameter
2018-09-27: >>> V3 is here! <<<
BIG THANKS TO rshartog FOR HIS MAKE AND HIS SUGGESTIONS FOR IMPROVEMENTS!
- Filament entrance is conic now (with round edge) to prevent overhangs at the beginning of the print
- gave 0.2 mm more space between rolls to avoid friction when print quality is bad
- made a new filament guid to insert a 4 mm PTFE Tube for less friction
2021-01-08: >>> Additional versions of V3 are here! <<<
It was told within the comment section that it is not possible to really tighten V3 against the table because the thread was too long. I added all 3 versions with 2 mm less length between thread and top (see preview pictures). So now you will be able to tighten the nut against the table!
