Micro needle roller Case Sleeve Protection Derma roller 0.5mm 1.0mm 1.5mm

thingiverse

Bought some micro-needle rollers off ebay. Great hang for buck however the vacu-formed plastic insets they came in provide little to no protection and risk bending the needles during handling and storage, so I designed a simple protective sleeve. Easily clears up to 1.5mm needle lengths. Friction fit. Simply slides in and out of the one open side. Open frame so it can dry after cleaning.
