prusaprinters

<p>A mostly 3D printed whetsone sink bridge that is used to securely hold most sizes of whetstone over your sink so you can sharpen safely and easily. &nbsp;The stls provided are 59mm wide (to suit the generic two-sided soaking stones available on amazon) and hold anything thicker than 7mm.</p><p>Very much inspired by <a href="https://www.thingiverse.com/mikechenders1">mikechenders</a> design <a href="https://www.thingiverse.com/thing:4772858/files">here</a>, but designed from scratch to be adjustable, easy to use, and built from what I had on hand. &nbsp;You can see what r/sharpening had to say <a href="https://www.reddit.com/r/sharpening/comments/rzy9u9/3d_printed_whetsone_sink_bridge/">here</a>.</p><p>There are two versions, one which uses printed threads for M5 and one which has 6.6mm holes for M5 heat-set threaded inserts (I uses the ones made by <a href="https://www.youtube.com/c/CNCKitchen">CNC-kitchen</a>). &nbsp;To make the sink-bridge you need the following:</p><p>Always print:</p><ul><li>sink_corner_narrow_top</li><li>sink_corner_narrow_bottom</li><li>sink_corner_wide</li><li>m5_socket_head_thumbscrew (x2)</li><li>soft_jaw (x2) - print in TPU if possible</li></ul><p>If you want to use threaded inserts (recommended)</p><ul><li>quad_joiner_threaded_insert</li><li>whetsone_holder_both_threaded_insert</li><li>whetsone_holder_narrow_threaded_insert</li></ul><p>If you want to use printed threads (does work but not as easy)</p><ul><li>quad_joiner_printed_threads</li><li>whetsone_holder_both_printed_threads</li><li>whetsone_holder_narrow_printed_threads</li></ul><p>Hardware required</p><ul><li>M5 socket head cap screws (3x25mm for the ends, 1x15mm &amp; 1x20mm for the thumbscrews)</li><li>M5 nut (3)</li><li>M5 set screw (4x12mm)</li><li>10mm rubber feet (optional)</li><li>M5 heat-set inserts (6, optional)</li><li>12mm round bar approx. 30cm: PVC, aluminium, steel etc (4)</li></ul><p>I have provided both the .f3d and .step files so you can easily make changes to suit your needs. &nbsp;The Fusion file is almost completely parametric (and hopefully very robust) so it should be easy to change things like widths and heights by simply changing the parameters. &nbsp;If you can't make any changes please leave a comment and I will be happy to make them for you.</p><p>I printed this from eSun PETG with the soft jaw in TPU but any material should be fine.</p><p>Happy sharpening!</p>
