Modular 19" Rack Case for Musical Gear

Modular  19" Rack Case

This modular rack case is the perfect solution for storing and organizing your musical gear. It can hold up to four independent modules (4U), and multiple cases can be stacked together and reinforced with steel threaded rods for added stability. The connecting bolts and nuts are designed for M5, and either standard or nylon nuts can be used.

This rack case can be printed from either PLA, PETG or ASA but if you are using a Prusa MINI printer, be sure to disable skirt for this print. Reccommended nozzle is 0.4 and layer height 0.2. But 0.6 nozzle and 0.25 Draft is still doable.
