Tutorial for OBI4 (2018 - 2023) Master Chassis
Fully removable chassis core, optimized for Neopixel install with a removable battery and a cool Crystal Chamber cage design with magnetic door and spinning insert.
This chassis is compatible with both 89Sabers K4 (2018 - 2022) and Korbanth OWK4 (2021).
GOTH-3Designs cannot be held responsible for any mistakes made by DIYers during their install. You must have a good understanding of what you’re doing, of the components used and the safety measures associated to them. Always wear protective gear when working on install (gloves, eye protection, …), GOTH-3Designs cannot be held responsible in case of accident.
Always use the smallest wires to make your install easier. There can be big differences between one wire type and another for the same AWG specs. PTFE Wires with the smallest OD are recommended such as those sold at The Saber Armory. A good wire management is also required, routing wires properly helps a lot saving space.
These instructions will not cover how to wire the soundboard, make sure to learn how to by reading the manual. We have also typical soundboards wiring available in the Padawan Tutorials. Always test your install along the way! Verifying that everything works after important steps is better than having to dismount everything because something wasn’t wired properly.
The following instructions are created from the Prototype install. Some very small adjustments were done on the final chassis and the pictures might not reflect exactly the final product.
– 2 x 4mmOD tube – 62mm length
– 2 x 4mmOD tube – 50mm length
– 2 x 1.5mmOD rod – 167mm length
– 2 x 1.5mmOD rod – 55mm length
– 12 x 2mmx2mm magnets
– 2 x 2020 pixel strips of 10 pixels
– 2 x 3.5mm tall brass tactile switches
DIY Build Instructions
Step 6: Wire the positive battery contact (with 2 x 22awg wires as shown). Then glue it in its slot. The long wire goes back in the tube while the short one will power the neopixel PCB.
Once glued in, the 2020 strips positive wire is soldered on top.
Step 7: Wire and install the NPXL PCB. The hilt side (short pins) or blade side PCB can be used – using a blade side PCB will avoid risk of shorts if the pins come in contact with metal.
Glue the PCB in its slot.
