Expandable LED Strip Holder (For Ender 3 and others)

thingiverse

Yes, it's another LED strip holder, and I know there are plenty of these on Thingiverse, but I couldn't find one that fits my preference for having more than one strip over the bed. Wanting to do timelapses, I thought multiple strips overhanging the bed would provide better lighting, and in my testing, it seems to be the case. The advantage of my design is that the bracket attaches easily to the top rail while holding the LED strip further out than other top rail solutions. This prevents the hot end assembly's interference with even lighting of the bed. Further, the extension arm, which snaps into the end of the bracket, can be used to attach one or more additional strips as needed. For the Ender 3, a second strip will end up above the edge of the bed when it's fully forward. To print this design, you'll need at least two LED Brackets and one LED Strip piece. How many pieces you need is entirely up to you. By default, the LED Strip is 25cm long, but it can easily be scaled down or up according to the length of your LED strips. LED Strip pieces are sized to comfortably fit a 10mm wide strip and should thus fit smaller strips if needed. The LED Strip thing is oriented correctly for printing, but you may want to add a brim or print it smaller if your printer can't handle the full height. My printer struggles as it approaches the 20cm mark. LED Strip Connectors can be printed to join shorter pieces together if they don't span the gaps between brackets. You can see an example in my provided pictures. All pieces should slide or snap together without needing glue, though some double-sided tape may be useful to hold strips to brackets and connectors to strips. Hot glue at the joints should also work well if necessary.
