Spool / Filament holder with bearing

thingiverse

Introduction ========= I designed this spool holder to remove the one from the top of my Artillery Sidewinder X1. Reducing the mass from the top, reduces the vibration of the arc when the bed is moving. This slightly improved the quality of the printings, mainly on the wall surfaces. Spool dimensions ============== Compatible with most of the spools in the market. Spool minimum inner diameter = 48 mm. Spool maximum outer diameter = 110 - [ (Spool real inner diameter) - 48 ] / 2 For example, for an inner diameter of 56 mm, the maximum outer diameter to avoid touching the base is 106 mm. Leaving a gap (safety margin) of 10 mm with the base. Bearings ======= Ball bearings used to reduce the friction as much as possible. The cost of them is very low. There are many different types compatible, not only ball bearings. Only need to respect the dimensions: 25 (inner diameter) x 47 (outer diameter) x 12 (width) mm Buying bearings can be intimidating if you have never done it before, but it is as simple as buying in Amazon. You just need to find a local business in your country or region. I particularly used this one in my model: 6005 Budget Open Type Deep Groove Ball Bearing 25x47x12mm https://simplybearings.co.uk/shop/p170105/6005-Budget-Open-Type-Deep-Groove-Ball-Bearing-25x47x12mm/product_info.html Cost: £3 each.
