it is suposed to be used flat on a wall. and cheaper to print.
it uses an 8mm screw bar with some nuts and a couple 608. like 4 . minimum 3.
and it prints with only 100grs of pla or some other fancy stuff u may have lying around. do not use steel. the part that can be used to screw this on a table is a bit heavy. but you may just do a hole on the table and use a couple of nuts. with the screw bar passing thru it
The "resorte finito" works. the other one.... i really have not tested it.
the spring is a LOT easier to print than the original. if using cura, just remember to turn off "combing mode" and "fill gaps between walls" . it will print fast and in superb cuality.
i print it with supports only on the center hole
check the design online to see how it needs to be assembled. there is a tiny tubular part that goes inside the spring that is very important. it allows the spring to freely turn if u screw hard the outside spool holder.
