Description
I had a spare 24v PSU from a 3D Printer build that I wanted to reuse for my Drone battery chargers. This allows me to plug in 4 of them at once!
Shopping List:
12/24v PSU - I used a 24v 15a 360w PSU
XT60 Mountable jacks, I used these: https://www.amazon.ca/dp/B09128LHGG/
An Inlet Power Socket, I used this: https://www.amazon.ca/dp/B0C142HCFW
18/16/14 AWG cables - Because the Voltage/Amperage will be low and the distance short, you don't need thicc cables that much. I used 18/16 internally and 14 for my external cables. I only used the 14 cause I had a crap ton of it but could've used a lesser gage to save space/weight
Heat-shrink tubing to protect the connectors
Also Needed: M4/M3 countersunk screws and a couple M3 heat sets. Oh and a 8amp 250v Fuse.
OPTIONAL: 2x 5 slot WAGO connectors - couple of slots that should fit the connector snug. Put a Dollop of super glue under it if you want to make it permanent.
Part Printing:
I used ABS for the housing, but could probably be PETG. I wouldn't use PLA here.
4 Walls
20% Gyro Infill
Scarf Joints Contour
You need to print the parts face down, a little bit of warping on the corners shouldn't affect the fit too much.
ABS loves to warp, some tricks to help with this model:
Set first layer to Concentric
5mm Outer Brim
50c+ Chamber Temp
Assembly Instructions:
0- Print Parts and screw on the upper cover the the PSU
1- Prepare 4x Internal Connectors and 1 inlet power socket:
2- Put in the Heatsets:
3- Insert and screw on the XT60 ports.
For the 2 on the end piece, suggestion is to place the part face down, guide it using the wires and then fingers/stick to push it into the part. Start Down and work your way up. It should fit snugly into the part and should not require any force once correctly lined up
For the Top two. Suggestion is to place the part with the ports facing up towards you, then pinch the XT60 between your index/middle finger and guide it under the plastic until you see it from the top, then line it up and push it into the housing. The Ports use an M2.5 screw to secure in place, it came with the jacks I ordered and might be different size for yours.
It will take a few tries since its not in an easy to get to get to spot. It does get a bit frustrating but you'll eventually get it. Took me a good a 30 minutes to get all them in, but was worth it!
4- Insert and secure the Inlet Power Socket, this is also the time to use the Wago connectors if you have them and secure them to the housing:
5- Wire the power supply, push in the cables gently with your fingers, then line up the housing with the PSU and insert it. Secure with 4x M4 screws.
Go slow and try not to pinch any cables.
That should be it! I also made myself some XT60 Cables to go along with it.
