Universal/Modular Spoolholder (integrated bearing)

UPDATE 24.11.2023

Thanks to the feedback from “chochi3D” i was able to optimize the overall stability of this spoolholder.

The following changes helped improving the stability:

• using 2 bearings for the one-sided mounting option (can also be used for two sided option of course)
• reuploaded all parts with higher stl resolution, which should lead to better optics and due to better surfaces also a better bearing seat
• uploaded all important bearing parts now with different fitting options in order to fit your individual environment

----------------------------------------------------------------------------------------------------------------

Overview:

Modular spoolholder with integrated bearings, that provides the following:

• reduce friction for filament pull
• different spool width and inner diameter possible
• different mounting possibilities (added "raw" adapter as step for custom solutions)
• fast and easy spool change

----------------------------------------------------------------------------------------------------------------

Technical Data:

• inner clamping diameter: 53mm - 84mm
• spool - width: 70mm max. with holder x 90mm
• spool - width: 90mm max. with holder x 110mm

----------------------------------------------------------------------------------------------------------------

Assembly Option 1: 

One-sided mounting [2x bearing highly recommended for this option]

**Note, that there are different bearing fitting types available for the “bearing-parts”

**Note, that you should only go for normal 1Kg spools when using the one-sided option

**Please make sure to use optimal assembly order for the one-sided option [see pictures]

Parts List:

• 1x “bearing-part1_[bearing(x2)]”
• 1x “bearing-part2_[bearing(x2)]”
• 1x “counter-part1”
• 1x “counter-part2”
• 1x “holder_90mm”
• 2x “clamp”
• “endcap" (either an existing one, ore use the raw step file for own solution)

Purchase Parts:

• 2x bearing 608-2RS
• 2x M3x20 cylinderhead screw
• 1x M3x25 cylinderhead screw
• 3x M3 Nut
