Kit Card Tree Parts, Instructions and 3UDC Pivot mounts

Welcome to the Kit Card Tree Library with the 3UDC pivot mount and information on how to build a display for your kit card or anything else you opt to attach.This project uses parts from several different projects.   You will print the same parts over and over as you make mounts.  Here are the links to those parts libraries.<ul><li><a href="https://www.printables.com/prints/126509">156DT

(This Library)</li></ul>There are hundreds of parts available to customize your build… plus things people will create.  Sorry for sending you about but not everyone will want everything and this way things are somewhat organized by type.So What is this:Kit Cards are fun little flat model pieces that turn into a piece of artwork designed by some talented people.  But what do you do with them when you are done?  The desk for week, a drawer?  Some you can hang from a string, but where?Now you can mount your completed kit-card on a display mount that you can plug into a 3UDC socket wherever you happen to have one:<ol><li>On a display tree</li><li>Wall  mount</li><li>desk pedestal</li><li>Side of a monitor</li><li>Wherever you want to render one.</li></ol>This project for you can be one piece you really want to display or an entire display that you build over time.  How to get started:Build a tower or don't.  You can use surface or table top mounts to get started.The 3UDC socket and parts are interchangeable.  The KitCard platform and sign brackets are customize for each kit.   There is a generous .4mm tolerance applied to the socket allowing for a high rate of success in print / fit and options for print orientation.The Pivot mount with the 3UDC clip.You have to attributes in picking your pivot mount<ol><li>How far do you want it go come out from the socket</li><li>How high do you want the platform to be above the socket</li><li>There are also extensions in the 3UDC Accessory Library</li></ol>The print… I have printed everything at .2mm layers with .4mm nozzle.  For the all of the swivel mount parts and kit card mounting parts I have printed no more than 20% fill.   If you print a 156DT tower read the notes in that library.SUPPORTS:  Support from build plate.  It should add the slightest of support material around the ball and maybe the sign platform.  If you don't support it the pivot ball will likely not form properly.  I had to raise it off the build plate to increase the turn angle.I have chosen an you pick the pieces model.  This way you can pick what complements your print results.<ul><li>File:

3UDC_pivot-arm-top-clip_##mm-out_height_##mm.stl</li><li>The Kit Card Deck of your choice</li><li>The Kit Card sign-holder… if you want.   You could glue the sign to the post.</li></ul>The sign holder is the most iffy to print for some people.   It is very small and has a lot of detail.  You can opt out and glue the sign to the post or design some other solution.  The front of the post has a small deck to stabilize the sign.   The sign-holders and most mounts were designed to be glue-less.The signs are the signs from the FULL KIT with the frame.   Cut the excess plastic from the edges of the sign leaving any frame if it has it.  Some designers use a frameless model and your sign holder will account for that.Where to find the kit card decksI have decided to put the decks as remixes with the posted kit cards.  With so many parts I can only maintain them in one spot.  If you have a mounting deck to contribute, put it with the kit card so people can see their options.  You can find the ones I have done any any people tell me about by going to the COLLECTION links in the links at the top.The Pivot and the spreader Install and AdjustmentThe pivot top gives you 360 degrees of rotation with 18-20 degrees tilt.   It is tensioned by a pin you drive into the ball to wedge it apart.  This is a DISPLAY PIVOT, not a constantly adjust tripod style pivot.  The pivot may take need to be gently rocked back and forth to loosen before a turn.  It sounds like grinding gears… but no problem, your objective is the position, not the tone of the turn.  Wedges are inserted from the bottom of the pivot.  I originally had it enter through the top, but you could not easily change it while your kit-card was installed.The PLA will loosen under the pressure, using a tight pin will reduce a need to replace the pin.  You can put a rivet in the pin or not, the pressure will hold it.   To remove the pin push it out at the base and pull.   If you have to put a larger pin in, you should find this is only necessary once.   There are multiple pins to choose from in .2mm differences in thickness (the layer height).  The hole goes on the bottom.Inserting the spreader.   Put the pivot platform on, with or without your platform attached.  Align the spreader towards the center of the pivot from the bottom between the tongs… give it a push.  If it stops… try to keep it from jamming against the pivot… then gently turn the pivot platform a half turn or so… and push in further… once it clears the base of the tongs groove, push it in and secure with a rivet if desired.Adjusting your deckI printed lots of rejects to get decks that fit the models well.  If you find it loose and it has long arms to hold the model you can momentarily heat and form the fingers closer… Momentarily on small pieces is brushing a match past.If the arms are two tight and short:If your model has tapered wings or mounting points, try sliding the narrow part in first then clicking the other side in.   Filament RivetsThe assembly is held together with… Filament Rivets.  These are pieces of filament where you use a hot iron… like a soldering iron… set to the lowest temperature if you have that option,<ol><li>melt one end to form a nail style head, </li><li>Let it cool</li><li>insert into the assembled parts</li><li>Trim it to about the thickness of a piece of filament</li><li>Seal it together melting the other end.</li></ol>A small set of side cutters can trim the ends off the rivets and release the parts.TREE Parts in the SAMPLE photoWhile I have created a wide variety of sizes, my strategy for my main Kit Card Tower was a compact tower with lots of planes. I used a 10 position 156DT_3UDC_Click-ring_114dia_10-station-Slots.stlI put the smaller planes on a 3UDC_pivot-arm-top-clip_00mm-out_height_31mm.stl pivot arm keeping the small planes low and close to the hub.  I then used a 3UDC_pivot-arm-top-clip_25mm-out_height_50mm.stl in the positions in between to keep them above the inner and low enough I could get another deck above.   You can also use a 35mm out arm or if necessary put a small extension on ones you need.Spacing I found with the parts above  156DT_shaft_085mm_sqr_105_spacing_for-20mm-high-hub.stl shaft to leave just enough space.  For details on tower attributes please refer to the comments in that library.GLUE on Pivot OptionSO far I have designed 57 or so custom platforms.  Except for two, all are designed to hold the model such that you can remove the model.  I have included numerous GLUE-ON pivots.  If you don't want your models to be removable from their mounts, you can use those or ones you design to glue them on.  See the developer's library for a blank with no holes to help design your own.Deck Holes Spacing for make your ownIf you are attaching something new, the holes in the pivot platforms I am posting are 15.572mm apart on Center.  Sorry… I did the spread as a percentage of size months ago not realizing the odd math.  The hole I cast is 2.1mm in diameter.Credits:While I do not modify or re-print any kit cards, the creators of these cards clearly put a lot of work into them.  Take  a moment to show them a result or two.
