Alfawise U30 - Bicycle light mount (round r=12,5mm)

thingiverse

I needed to illuminate the build area so I could see what the machine was doing with both hands free, so I created a mount for my bicycle light that attaches to the aluminum extrusion. Since the light is quite heavy and gets extremely hot when left on for an extended period, I didn't worry about making it lightweight. We'll see if the heat will be too much for this PLA material. The part that attaches to the extrusion is 25mm long, providing a secure grip, and has a chamfered edge of 1mm on one side to make insertion into the tight profile easier. The part that prints against the bed also features a chamfered edge of 1mm all around to facilitate removal from the bed after printing. In retrospect, I should have placed the chamfering on the opposite side of the profile as it would be better to mount this design from the rear of the printer due to interference: https://www.thingiverse.com/thing:3468782. However, it still works mounted from the front if you slide the mini drawers a little further back like in the picture. The circular mount on the light is 25mm in diameter, and I conducted a quick test to determine how much of a gap I needed to add in a hole printed upwards with support. I tried diameters of 25mm, 26mm, and 27mm and concluded that with my printer and settings, the best diameter for this purpose is 25.5mm. With a hole of this size, you don't have to force the light in but it remains sturdy enough to prevent excessive movement and maintain proper direction. This allows me to adjust the "z-direction" of the light as well, thanks to its handy zoom feature, enabling me to aim higher when zooming out. The layer height of 0.3mm is clearly visible on top of the print and appears somewhat coarse but was not a primary concern during design. I focused more on functionality than aesthetics. Now, I need to figure out how to power the light from the printer's power supply. Unfortunately, I'm not well-versed in electronics. Any tips would be greatly appreciated!
