Scythe heatsink pushpin replacement intel retention (Shuriken , Katana, and others)

prusaprinters

<p>My scythe shuriken rev.B has one push pin broken, and other two that not hold very tight, the push pin system is specially a pain in small cases without any space to action and twist the pins I make this for completelly replacement.</p><p>Hole distance is adjustable from 70mm to 80mm (yeah, you can use with newer intel sockets :D)</p><p><strong>You need M3x40 screws and M3 nuts, and spring or silicone tubing from vacuum pipes of a car (8,5mm OD), prefered springs, but I don't have and use this.</strong></p><p>See mounting images for instructions.</p><p>You need fit silicone tube or spring between the two cups, insert te M3x40 screw, insert the mounting coupler and recommended to fix in place with the small rings for easy installation later.</p><p>For me, 14mm of silicone tube works flawless, you can use less but I need to leave flat the rear of the board because my case has two 2,5" drives just here. If you use more than 14mm of silicone tube the installation may be difficult and you will need to apply some strenght to pass the board holes.</p><p><strong>PRINT IN HEAT RESISTANT MATERIAL !!! AVOID PLA !!!, use at least Petg, ASA / ABS highly recommended.</strong></p><p>I made some test and two final tests, one with PLA (blue in photos) only for mounting test and the final version with ASA. (White in photos). Tested various lenghts of silicone tubing, less than 10mm result in poor spring effect, 11-12mm results in screw threading a lot, ideal 14-15mm , more than 15mm results in needed apply to much force or use longer screw.</p><p><strong>Use supports from base.</strong></p><p>&nbsp;</p>
