I made some lights to help illuminate your pinball playfield.
The photos don't really do it justice due to my phone camera using HDR/over-exposure to capture the playfield in low light. However, they make a huge difference and greatly improve video capture where exposure is short.
These are designed to be used for streaming or recording pinball play where better light is temporarily needed and can be moved between machines.
They attach to the outside of the cabinet using magnetic tape. They can then fit a regular LED strip < 11mm in width.
The piece is only 235mm long, but you can extend or contract the length along the axis to fit your print bed.
For me, 4 of these printed well standing upright in my Ender 3 v2 (using a large raft to adhere).
I then glued these together end-to-end with superglue and relied on the magnetic tape and LED strip to hold it together. They are plenty strong enough, but I wouldn't go swinging them around.
