Geeetech Prusa i3 - X and Y axis idler pulley with push pin
Description
I'Ve Had Problems With The Idler/Belt Tensioner On My Geeetech I3 Pro B Printer. So I Made This Using Some Old Rollerskate Bearings. To Make This You Will Need One 608Zz Bearing And 6 Grams Of Plastic. The Bearing Is Kept In Place Using A Push Pin. It Works For Both X And Y Axis, Allthough On The X Axis I Loose About 10 Mm Of Buildspace Since It'S Bigger Than The Original. Once Assembled, It Can Be A Little Difficult To Take Apart Again, But You Can Lift The Pin Using A Small Flat Screwdriver. After That It Should Be Easy. The Pin Is Not My Design. The Pin Came From This Spool Holder Made By Dwonh, Which By The Way Works Perfectly.
