Works with LED strips that come on the small black spools. Mine measured 9.3 mm across and about 2.5mm thick. Purchased from walmart for ~$6.
Printed in PETG so they'll have some heat resistance and flex. Be careful when driving screws, overtightening will break the retainers in half.
Screw holes are 4.3mm
