Customizable Prusa MK3 Y-axis Bearing Holder

<p>Thanks to inks007 for this well made design (Thingyverse thing:2969556).</p> <p>I used it for with Igus drylin RJ4JP-01-08 bearings. And it works very well so far. I upgraded the x- and y-axis with RJ4JP bearings and it's super quiet now, doesn't have any play and runs super smooth. The design should also work with the standard bearings.</p> <p>I did have some issues with the original design:<br/> When I installed the y-axis on my new MK3s I noticed that it rubbed against the frame. Picture of it is attached.<br/> After learning how OpenSCAD works, I figured out how to adjust the design accordingly.<br/> Now the remixed version won't rub against the frame anymore.</p> <p>Everyone should just need to adjust this one parameter:<br/> bearing_od_loosen -&gt; adjust it according to the bearing, printer settings and filament material</p> <p>Sadly the naming of the stl files is confusing. I uploaded the files and prusa renamed them. They automatically changed +0.1 to +1 with means the diameter of the hole for the bearing is 0.1mm larger.<br/> There are five versions:<br/> -1 = -0.1mm smaller diameter<br/> 0 = normal diameter<br/> +1 = 0.1mm larger diameter<br/> +2 = 0.2mm larger diameter<br/> +3 = 0.3mm larger diameter<br/> Print the version whitch makes a nice press fit for your bearing.</p> <p>What you need for this design:<br/> 6x M3 16mm-18mm screws. (Use washers with the 18mm long screws otherwise they will hit the frame)<br/> 6x M3 nuts</p>
