This is 2 designs for LED supports to mount on the Z axis frame for a Monoprice 13860 / Wanahao i3.
I bought some 5V LED lights from Amazon and wanted to mount them around the Z axis frame so I can more easily see the print. The LED's are in a string, roughly 36 inches long with a Velcro backing, the mating Velcro strip with adhesive backing is included. The string is terminated with a male USB connector for power (docs say 1.0 A). The link to the LED string is below.
The supports are roughly 3-1/2" long; you make 3 per side and clip them along the Z axis frame.
The first design (shown in the application pics) clips along the edge placing the LED's toward the front of the printer. The top of the LED's are flush with the edge of the frame.
The StraightSupport2_1.STL file includes a couple of updates. The first update is to narrow the ledge the LED's sit on so the LED's can be mounted on the opposite side of the Z axis frame. If the original design (not included) was mounted on the back face of the Z axis frame it would crash with the X axis trolley. So I narrowed it by 1mm - it will be snug but should clear . I also moved the LED away from the inside edge of the frame so you don't catch as much direct light from the LED's.
The second design (includes MK3 for Mark 3 in the name) includes a lip on the front edge of the LED ledge and includes the 'LED farther away from the Z axis frame edge'. Note this design includes the entire width of the original LED ledge so you won't be able to back mount (LED's to Z axis screw side) the LED's. The lip provides a bit of a cowling so you're not staring directly at the side of the LED's.
Both designs are intended to be a simple clip design. They will not fill in the top corners of the Z axis as the thickness of the corner is two plate thicknesses and I didn't include that in the design - works well enough without it.
I had a view issues printing these parts - the replacement printer to the original (burned out the heated bed controller) has been a beast. I did a 3x3 grid of the parts and ended up putting them on a raft - there isn't much cross sectional area so getting them to stick was not easy. I have a pretty thick shell set on my slicer (Cura) so they printed as solids (cross section of the part is 1.34mm).
The designs were done in Solidworks 2013.
