Following Grimm's traditions, step files are better than stl. Please thank Grimm/Nash for the remake. This wouldn't be possible without his step files: https://www.printables.com/model/865559-onewheel-pintx-z-battery-box-remake
I made the round corners near the BMS area “squarish, " allowing for the fitment of 40 18650 cells in the box (eh…not really). The layout does not leave much room for tape, wires, etc. I realize a simpler layout by offsetting each alternative p group by 6mm higher (too much and you need chi hammer). So I built the weld frame to help lay them out with this offset. I printed the padding to relieve the pressure/stress on the alternate p group.
2 things to note:
- The box is to be used with the TFL float plate to help protect the box/battery. You'll want to chop the front and rear off. Remove the adhesive since they are now bolted on. Place the front float plate over to the rear float plate and mark the 2 missing holes so you can drill it out.
- You'll need to cut the prongs off of a charge port (I'm using gx12-4) and make them verticle (see picture) or else they dig into the battery.
Files included:
- Weld Frame - Recommend pla. Uses 4 x m4 screws and nuts.
- Pad - Recommend tpu. You can use scissors to cut these tpu pads if wires are in the way, etc.
- 8x Bottom (I used 7x only due to how I routed the discharged xt60 wires)
- 2x Corner
- Bumper - Recommend printing this with 7 walls and 60 infill with cf pa, cf pc, etc.
- Box - Recommend printing with 5 walls and 40-50 infill with cf pa, cf pc, etc.
- You'll need 2x m4 heated insert for the float plate.
- The screws for the float plate will be 2x m4 14mm and 2x m4 60-65mm (mine needed 65mm)
Offtopic:
Added 15s2p 21700 box step file. The only difference between this and the 20s2p 18650 box is this one has the charging port bracket. It is meant to be used to do the half-gallon battery build: https://docs.google.com/document/d/13RFsZmAaAs7-BoWP7CTlxNfn-3OYNUN_Gvy2KQUzqg4/edit?usp=sharing
