UcPure Holder

Holder for the UcPure ultra capacitor power supply 

UPDATE 10/10-24:

• CENTER PIECES ADDED TO BUILD ONE DOUBLE UcPURE (see below step guide)
• SMALL UPDATE TO ORIGINAL UcPURE HOLDER

Not for Commercial use - DIY only!

WARNING – Ultracapacitors are very dangerous! EVERYTHING IS DONE AT YOUR OWN RISK!

DISCLAMER: Working with Ultra Capacitors can be extremely dangerous and potential lethal!
Do not work with ultra-capacitors and this bracket or anything related to it, if you do not have any experience in working with ultra or super capacitors. This is not a tutorial and is referring to the holders only.

ULTRA CAPACITORS MUST BE FULLY DISCHARGED BEFORE ANY WORK CAN BE DONE. LOOK AT THE MANUAL ON HOW TO DISCAHGE AND WORK SAFELY:

Don't have a 3D printer your self? I am selling a small batch here: https://www.diyaudio.com/community/threads/3d-printed-holders-for-the-ucpure-power-supply.412302/

The holders are made for the wonderful UcPure ultra-capacitor power supply designed, made and sold by IanCanada. The power supply consists of PSU board and a balancer board UcBalancer:

HIGHLY RECOMMENDED: Tutorial on how to assembly the UcPure PSU can be found at the youtube channel of Gabster:

Made to be used with ultra-capacitors like Eaton XL60, Tecate Group TPLH and similar with a diameter of Ø60-61 mm and a length of min 138mm.

To have a better and more secure way to fix the UcPure into an enclosure I designed these holders.
The holders are identical from left to right and consist of a lower and upper part.
For a simpler and shallow fit the lower part can be used separately without the upper part and the fixing of the ultra-capacitor can be done by zip ties (see last picture).

The holder can be secured to a bottom plate with 4mm screws in two configuration;
• at the outer flanges
• at the countersunk holes at the curvature.

The UcPure PCB can be fitted in two positions at the top of the upper bracket or at a vertical position at one side.
All pilot holes for fitting the PCB is Ø2mm.

How to (also see pictures):
1: remove any unwanted material.
2: drill pilot holes to desired size
3: insert a M4x50 – M4x65 screw into the top holes at the lower part and screw on a m4 nut
4: pull the nut back into the bottom hexagonal holes. Remove the M4 screw
5: mount the Ultra-capacitors into the lower brackets. Use of a single layer or more of Insulation/fabric tape wrapped around the capacitors is highly recommend for a firmer and protective fit. Slightly different prints will occur when using different printers. More tape may be necessary.
6: mount the UcBalancer boards according to the manual (OBSERVING CORRECT POLARITY): https://github.com/iancanada/DocumentDownload/blob/master/UltraCapacitorPowerSupply/UcBalancer/UcBalancerManual.pdf
7: fit the upper part and screw the previously M4 screws in to clamp the brackets together.
8: feed the balancing cable through the holes of the lower part and connect it between the two balancing boards.
9: mount the UcPure PCB to either of the two top positions or at the side for a vertical mount. I recommend using a 2mm plastic washer between the PCB and holder. I have used four screws to secure the PCB and with a overhang towards the wire connection for the capacitors. This gives a really short wire distance.
10: add protective caps to the M12 bolts for added safety

CENTER PIECE to build one double UcPure:

A fellow DIY'er asked if it was possible to stack two UcPure holders on top of each other to build a double/quad UcPure. It is of course possible but I created a center piece to make it easier. The center piece is split into two part for easier printing and must be joint together afterwards
The center piece is compatible with older printed UcPure holder.
The new UcPure Double is designed to have both UcPure PCBs mounted on the side.

How To (see last pictures):

• Print 2 x center piece and 4 x dowels to make a one center piece (print in same direction as the original UcPure Holders. Dowels printed with flat side down).
• insert the dowels into one af the pieces and then glue the two center pieces together (I recommend a solvent for acrylic similar to Weld-On 4 or Acrifix 192). They could also be screwed together instead of gluing using two M4 screws and nuts. Both ways works just as good.
• insert 4 x M4 nut at the cavities on the side 
• insert the now finished center piece in between a lower and upper part of the original UcPure holder
• insert M4x50-M4x65 screws from the button of the lower UcPure holder (remote m4 nuts in lower part if inserted) and feed them through the center pieces and screw the together.
• do the same with the upper UcPure holder.
• Now you have a finished Ucpure Double holder ( thanks for the picture Jay:-) )

Enjoy :-)
