3UDC and 156DT Developers Library for Clips and Display Tree

Welcome to the Developers library for the 3UDC clip system and the 156DTmm display tree.

Both of these systems involves lots of components and I wanted to put parts and information needed to create things in a non-end user library.

These are links to associated libraries

• 156DT Display Tree Library (tower parts)
• 3UDC Accessory Library (3UDC Connector Accessories)
• PrusaPrinters COLLECTION Library of KitCard Platforms (platforms for Kitcards)
• Thingiverse COLLECTION Library of KitCard Platforms (platforms for Kitcards)
• 3UDC and 155DT Developers Library (This Library)
• Kit Card Tree Parts and the 3UDC pivot platform (kit card tree and the 3UDC swivel)

In this library you will find dimensions, STL's you can import and other information.  I look forward to what people come up with.

3UDC clip

The 3UDC clip is 3mm wide.   The clip can be printed flat on ether side, standing up, or on its top with no supports.   This is possible because the socket supports the clip being on the top or the right side.  3UDC has a 1.6mm wall on the top and sides, the base can be whatever thickness you need.   

The tolerance on the 3UDC system is applied to the socket.   By default .4mm was built in.  While a little on the wider side of tolerance, I chose it as the default so most user may get usable results without tinkering.    Unfortunately putting the clips on the outside of the socket means the tolerance is in the formula for the clip design.  The clip gap has to take into account the wall thickness. 

The sockets print upright or on their face with no supports.  They can print on their left side on printers that have good bridging attributes using the default tolerance.  A little center support if required.

The socket holds the weight of the content, not the clip… so no suspending things with clip entrance facing downward.

3UDC clip with tension ridges

The tolerance is built into the socket so that a clip always fits.  There is enough tolerance to allow a socket to be printed on it side with no supports and the clip still fit.

For most installations it is no issue, but long objects plugged in may suffer from amplifications of movement at the end… so the tension ridges are small enough to allow a slide in, but reduce that motion.  The are small enough they can be easily reduced or removed with a blade.

Floating Adapter Plates

A floating adapter plate allows you to take a Floating adapter slot and drop it onto the side of any model you are printing at any position above the bed.   After the print, you can print the floating adapter plate with a 3UDC connector on it and slide it into the slot.   This means you can print your part in the optimal upright position and still add a connector.

Floating adapter slots for round items come optimized for the diameter of your object.   For flat surfaces there is just one offering.   For flat surfaces you can add more than one adapter slot.   I guess you could do that four round as well so long as they were one above the other.

Ideally you embed the slot into the side of your print until the entry is almost flush.  If you are using Prusa Slicer, select the SLOT and the object to bond it to, right click and MERGE.   After merging you can move the slot to any position above the bed along your object.

156DT

The 156DT is a 15.6mm modular tower.  Display tower can accommodate the 3UDC socket, pinned wheels, bowls, trays etc.  

The tower.  The original design was just the round pin with the wedge to give some tension and present spinning.   At 15.6mm bridging was nominal on the holes however the inconsistency varied between materials making for mixed results.   The wedge was added to the top.  This cuts directly into the bridge area..  the wedge does nothing operationally, but it has to exist in the hole, on the wedge and on accessories to go over the hub.

5UDC Clip

I am adding some 5mm clips.  These are 5mm wide instead of 3.  You can see I used these extensions with the 5mm to 3mm adapter to pose the Kit Card Planes in front of the tower.

** Other than the adapter 5UDC to 3UDC the sockets and clips are NOT interchangeable.  They just share the same design attributes.
