3mm LED Holder

Secures LEDs against being pushed back in to the mount, since it features little latches. Fits in an 5.5mm hole with at least 1.0mm material thickness

Printing is best be done with a 0.4nozzle and layerhights from 0.12-0.2mm. However, 0.12mm works best. No support needed. PLA wokred just fine with me but since the holder features little latches and has to be snaped in place, PETG might be more suitable for this job. Due to its smal size, it might also have some stringing but this does not impact its function since the latches do mostly still move. Should also work with resin
