FAQ
▶How much does it cost to print?
1-2kg of filament. MASS is tested on generic PETG. You can typically find 1kg rolls for $13/kg each (Link), $12/kg if you buy 4 (Link), $10/kg if you buy 10 (Link).
▶Premium vs Free difference?
Premium has PCIE slot support, holds 5 drive per caddy, supports up to 13 drives, has handles, extra 2.5” drive adapters, Flex PSU bracket, addon Fan modules and ongoing updates. It supports development of more awesome designs.
▶Can Free version use premium modules?
No. MASS Free Version was the original model without PCIE slot, making it slimmer by 11mm on the width of the tower, and thus not compatible with the PCIE equipped Premium model.
MASS Free is still a potent enclosure with 4x3.5” bay support and can technically stack up to 8 drive bays using M.2 HBA.
▶Is MASS durable?
MASS is built with an intimate understanding of the non-anisotropic strength properties of FDM. The parts are appropriately designed to overcome layer splitting issues by orientation and print settings. MASS development is committed also to ongoing improvement to ensure it is a durable and reliable option for your NAS setup.
▶How to connect more than 4 drives?
To expand the beyond the 4 sata ports on most ITX motherboards, you can install a Low profile PCIE SATA card on the premium model. You can also use an m.2 SATA controller to add a few more.
