Ymiko Boost Converter Module XL6009 DC to DC Case for 3.0-30 V to 5-35 V Output Voltage Adjustable Step-up Circuit Board by IsmotheVirtahepo

If you buy this awesome board from amazon or ebay, it comes without a case. So i designed a nice little case for it. Fittings are tight, case stays closed without glue or anything. Printing the "lid" requires supports and for nice clean outcome, your printers supports need to be adjusted well. But overall, easy to print and does what it needs.
