In the last post, I wrote about how I quickly made a holder for a 3kg filament spool (from furniture hardware joker). The stand technically works, but to improve printing, friction needs to be reduced, and it must be ensured that the spool does not get caught and stop spinning.
On makerworld, there are many different options for spool holders of the size I need. First, I decided to try a holder that:
prints on one plate
does not require bearings (too lazy to search / buy)
Here is the link to the model. In the reviews on makerworld, I saw real photos from a user with the PrintArmy logo on their avatar. So +1 to trust in this model was added (but there is a nuance).
I have PETG Military Edge filament (3kg).
ширина катушки ~105мм
висота ~266мм
Spool dimensions:
width: 105mm
height: 266mm
I printed the spool holder, started measuring the spool...
The design is a couple of millimeters smaller than needed for this spool. I printed this holder thinking that it has some margin of height and width and everything would be fine.
In fact, the Military Edge spool just stands in this design. It spins, of course, if pulled. But we need to reduce friction so that the printer can properly pull the filament.
Time and filament spent on this thing. So it was decided to modify it. Zip ties came to the rescue:
The zip ties provided the needed couple of millimeters for the spool to hang. And it seems that the holder spins better on 4 zip ties than without them (smaller friction area).
Regarding the review I fell for. It seems they also added something (*°ｰ°)ﾉ
