Modification to X-Axis Belt Tension Fork to allow cogged bearing for Startt

thingiverse

I decided to change the idler bearings to flanged cogged idler bearings. I read somewhere that these cogged bearings run smoother with cogged belts than the stock smooth bearings, I purchased the following bearings from Amazon for $9 US delivered: BIQU GT2 20Teeth 5mm Bore Aluminum Timing Belt Idler Pulley for 3D Printer 6mm Width Timing Belt (Pack of 5pcs) www.amazon.com/gp/product/B01H3DNKYY/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1 These cogged idler bearings are wider than the stock bearings. The stock Y axis idler mount and the Y-axis belt tensioner mod designed by Bkult3 both use the huge spacing washers with the stock idler bearings. Removing the large spacing washers allows the flanged cogged bearing to fit perfectly. The attached is a modification to the tensioner fork in the X-axis belt tension for Startt by Bkult3. It allows the wider flanged cogged idle bearing to fit. This is just a easy tweak to Bkult3 great design. The tensioner mods of the X and Y axis work great and I thank Bkult3 for his effort. I don't know if the cogged idler bearings really run any smoother with the cogged belts, but I'm happy with it. I also think the flanges on these bearings also cause less wear on the belts than the occasional rubbing on the printer guides with the stock ider bearings.
