<p>I am so totally impressed with <a href="https://www.prusaprinters.org/social/24779-andrei/prints">Andrei's</a> <a href="https://www.prusaprinters.org/prints/27216-bag-clip-print-in-place-cam">Bag Clip</a>. &nbsp;It is one of the most clever designs I have ever printed. &nbsp; From the moment I took it off the printer, I wanted to completely understand how it worked and how Andrei designed it. &nbsp;I spent weeks building his design up in Solidworks, trying to understand the math involved in the CAM mechanism. &nbsp;Once I had his model rebuilt, I then started playing and having fun with tweaks and changes. &nbsp;You will notice the v3.04 on the inside of the lever; there were a LOT of versions.&nbsp;</p><p>In addition to the obvious change of giving the clip a dinosaur theme, I also:</p><ul><li>Designed a Break-Away support tab (Easier to slice and remove supports after printing)</li><li>Increased the two post sizes to 8.5mm (Stronger clip is harder to break)</li><li>Added a chamfer to the base/top of the posts (Makes breaking parts loose easier after printing)</li><li>Added a completely different ‘teeth’ design (aesthetics and gripping the bag better)</li></ul><p><strong>Printing: </strong>I print these clips with a .2mm layer thickness at 20% and they are very strong. &nbsp;I've included two GCODE files for PLA which is what I print all mine in. &nbsp;</p><p><strong>Tips:&nbsp;</strong></p><ul><li>After printing, break off the support, and squeeze the entire print like you are closing a nutcracker.</li><li>The further you put the bag into the Dino's mouth, the harder it is to shut. &nbsp;If you have a really thick bag, don't put it all the way in. Finding the right jaw strength was one of the causes of many versions.</li><li>The best materials I've found to use are matte PLA's - My favorite is<a href="https://www.matterhackers.com/store/l/proto-pasta-highfive-blue-metallic-htpla/sk/MFW1GMS9?rcode=PPCADS"> Joel's High Five Blue</a> (pictured) from <a href="https://www.matterhackers.com/store/l/proto-pasta-highfive-blue-metallic-htpla/sk/MFW1GMS9?rcode=PPCADS">Proto Pasta.</a></li></ul><p><strong>Update 04/25/21:&nbsp;</strong> I have uploaded the STL's for multi-color, the MK3S-MMU2 .gcode, and the SLIC3R Project files for both a single print and printing a lot of five clips. &nbsp;The MMU2 uses the first three positions. &nbsp;Have a look at the attached image for reference of which color is where: Purple MMU2 position #1, Blue MMU2 position #2, Orange MMU2 position #3&nbsp;</p><p>&nbsp;<strong>IMPORTANT NOTES: </strong>The Multi-Color STLs are only for multi-color printers. &nbsp;They can not be printed separately and assembled. &nbsp;This design is PRINT-IN-PLACE only. &nbsp;Secondly, I have had a lot of issues printing multi-color. &nbsp;Make sure your print bed is very clean. &nbsp;Whatever your cleaning process, I suggest you do it before this print.</p>
