Silent wheels for the Prusa IKEA Lack Enclosure Spool Holder
Description
After Having Finished The Prusa Lack Enclosure From Https://Www.Prusaprinters.Org/Cheap-Simple-3D-Printer-Enclosure/ (Things On Https://Www.Thingiverse.Com/Thing:2864118) I Printed The Adjustable Spool Holder From Https://Www.Thingiverse.Com/Thing:2867521 Which Is A Really Clever Idea For The Lack Enclosure. But The Noise Of The Spools Scratching On The Non Spinning Wheels Was A Bit Annoying. (See Video - The Original Wheel Isn'T Moving) So I Replaced The Axles And The Wheel By Using A Ball Bearing (8X22X7) With A Printed Tread And A Matching Two-Part Axle. It Fits Perfectly Into The Holder And Is Really Silent. The Treads Of The Wheels Are 9Mm Wide And Have A Small Lip To Center The Ball Bearing. Just Slide In A Bearing (Usually No Need To Glue It - But Depends On Your Dimensional Accuracy), Insert A Square Nut In The Axle Part, Insert Both Axle Parts In The Bearing And Screw It Together. Maybe Consider To Sand The Tread To Make It Smooth Happy Silent Printing :-) I Used A M3X20 Screw With A M3 Square Nut To Assemble The Axle.
