Extension for dry MMU2S Buffer

prusaprinters

<p>This is my 11cm extension to Tobor dry mmu2s buffer.</p><p>I have a 60cm extended bowden tube going to the extruder so about 24cm more than the standard 36cm. This extension works very well and has exactly the right length for my tube.&nbsp;</p><p>&nbsp;</p><p>You can meassure your tube and just change the height with your slicer by using the formula:</p><p>Let x be your bowden length and y be your needed extension height: y = (x - 36)*11 / 24&nbsp;</p><p>e.g. your tube is 90cm so your desired extension length is y = (90 -36)*11 / 24 = 24.75cm</p><p>Remember to only alter the height and not the other dimensions. You also might need longer screws.</p><p>&nbsp;</p><p>I printed it without support and had to cut of some a few blemished since I was lazy. But you can optionally print it with support for the top screwholes.</p><p>Res .3mm pla&nbsp;</p>
