Updated Rostock Idler End for different ball bearing size
thingiverse
I made significant modifications to the original SCAD file designed by Johann, making it easier to change the Ball Bearing Bore size. If you're using a GT2 pulley with 16 teeth for instance, you'll need the new updated carriage that I uploaded and smaller ball bearings for the idler end. **Instructions** The modified file is identical to the original except for the different ball bearing bore diameter. The default size remains at 8mm, while an additional option is available at 5mm for use with smaller ball bearings that have an outside diameter of 10mm. To purchase a suitable bearing (5mm x 10mm x 4mm), visit: http://www.aliexpress.com/item/10mm-x-5mm-x-4mm-Silver-Tone-Sealed-Premium-Flanged-Ball-Bearing/1245802950.html For cost-effectiveness, I recommend using M5 screws instead of the standard M8 screws and bolts/washers. The M5 cap screw 25mm can be purchased here: http://www.aliexpress.com/item/free-shipping-12Pcs-25mm-Long-M5-304-Stainless-Steel-Hexagon-Socket-Head-Cap-Screws-M5-25mm/2048204191.html
