Big-Filamentholder with a twist

thingiverse

This is an elongated version of the "Filamentholder with a twist" to handle big spindles with approximately 10 cm width. Why did I do this: I ordered a 1.8 kg spindle of Wood Filament "Woodfill" from "colorFabb" and realized after opening the package that it will not fit my 8 cm axle and therefore not the old filament holder that I designed before. See pictures for size reference: The shown three spindles are: 1.8 kg, 1 kg and 500 g. Next to the spindles you can see both screws: The big one is optimal for 1.8 kg and 1 kg, the "regular" sized is big enough for 1 kg and 0.5 kg. It is possible to use ALL spindle sizes on the big screw but it will waste more space and take longer to print. This model is primarily for huge spindles (width > 8cm) that do not fit the regular filament holder with a twist. Everything smaller (up to 1 kg spindle size) can still fit the old one. _What was changed_ - The screw is longer (not a big surprise) - The position of the ball bearings is almost the same as it is with the small filament holder so that it still fits on the 8cm axle from Snapmaker -- To achieve the position deep down in the screw the hole is slightly tapered so that the ball bearing will drop about half way and then needs some "serious push" to lock in place (press fit) -- To check if it is all the way in: Insert the Snapmaker axle with the Thunbscrew on one end: If the other end sticks out the other bearing by approximately 1/2 mm it's ready to be used. - The screw head has a new small feature (a hole) so that you can use e.g. the Snapmaker tools to lock the spindle if you need to unscrew the nut. The filament spindle runs very easy on this construction thanks to the ball bearings. It is no problem that the width exceeds the length of the axle. I already printed a benchy with that new filament holder in place and it worked very well. Estimated print time: 9 to 10 hours.
