A year ago I changed the filament spool attachment from classic to vertical and upper, above the printer.
Why?
- the spool takes up space on the desk
- the spool unwinds as it pleases, which sometimes causes the rolls to jam
- I have a plexiglass case and I want to adapt everything to closing
But the main reason was jamming of the reels on the spool during printing. The worst part was when the spool was level. Filament coils fell off and were easily wedged. In addition, bearings in the middle shaft allowed the entire spool to rotate too freely.
OK, you can try with some sponges or rollers as a brake (I saw such projects on TG), but this is not a design solution. Just preventing problems.
Therefore, after testing a few ideas of colleagues with a central shaft and bearings, I decided to do something different.
What came out of it?
You can watch in the movie. The spool is a brake. Gravity only helps. I tested the diameter of the spool to make it rotate freely, but the weight of the spool braked it.
Thanks to this, I can safely leave the printer overnight without fear of seeing a plastic massacre in the morning ...
If you used my previous version, just print a new spool and tips. I did the project to use the previous arms.
I used bearings 8x16x5 mm x2. And glued them if necessary.
