This is my first ever 3d model, made in On Shape. Many thanks to @MakerSteve3D for uploading the z mount step files.
I know these could have been made much better or more efficient, however it does the job as it is and it was a fun little project.
I have modified the original top Z mounts to allow 2 threaded inserts in each and the left one also has a small hole for routing the power wires. The led bar holders are to be mounted on top and secured with 2 m3 screws.
BOM:
- Led strip for the appropriate length (~34 cm) and voltage (24v for mine)
- Alu profile for led strip. I used a generic one from my local hw store, rectangular shape external dimensions: 16 mm in width and 7.1 mm in height.
- 4 x threaded inserts M3 x 5.7
- 4 x M3x25 SHSC screws
- 1-2 m of wire, I used 0.25 mm2 (AWG 24)
- Mini rocker switch. The led bar is designed for one with 8.25x13.2 mm part no KCD11 (Warning! I've seen the same part with different dimensions)
Tools:
- Soldering iron (you can do it without, however…)
- hacksaw to cut the alu led holder
- Allen keys
Installation:
- Install the 4 heat inserts in the top Z mounts.
- Install the top Z mounts on the printer and make sure you align them properly.
- Solder the power wires to the led strip and install it in the alu holder
- Route the wires through the left holder and out the switch hole. The negative wire will not be cut and will pass through the switch hole
- cut the pins of the rocker switch enough to shorten it but make sure you are able to solder the wires on what's left.
- Splice and solder the (+)positive wires to the switch & insert the switch, make sure you do not damage the insulation.
- Route the wires through the left top z mount and attach the left led bar holder to the left top z mount.
- insert the alu led strip holder in both left and right holders
- Install the right bar holder on the right top z mount.
- Connect the wires to the printers power source ( you should know which ones are )
- Be happy in life.
Print settings
- I used ABS, the led bar will get pretty hot. I would advise against PLA
- 0.2mm layer height
- 40% infill
- 4 perimeters
- 5 top and bottom layers
Warning! You need to know what you are doing around electricals and soldering irons. Most solder contains lead, be aware. High voltage will kill you if you don't know what you are doing. I will assume no responsibility for any damages or injuries caused by implementing this project.
