Monoprice Maker Select V2 Part Cooling Solution

thingiverse

I've done tons of testing for part cooling and found this ductwork works really well. There are two things, REV 5 and REV 3. Both need a good 5015 Blower! REV 3 does nearly as well as REV 5. REV 3 lacks a center air outlet and is provided with and without a raft. REV 5 has a center air outlet and only is comes with a raft. Remove the existing blower and duct work. It uses 3mm screws to hold the 5015 Blower in place and mounting to printer. Drill out holes by hand or machine to clean them out. Use a 2.5mm drill bit or very close in diameter. The screws will self tap, keep the screws perpendicular to the hole. Be sure to use the correct length when mounting the ductwork to the printer so not to damage the blower. Parts 3mm screws of appropriate length & 5015 Good Blower (12V for MonoPrice Maker Select V2) Use ABS although PETG ought to be fine. I designed a raft and support into the model and found it came right off without difficulty when using ABS. Use cooling, for ABS set at 66% starting layer 3 or four. Use 100% cooling on bridges. My printer has heated internals, set at about 55C. You may need to add some support under the outlet nozzles. PETG may be harder to detach the raft and support. I only had to support the one high overhang and under the nozzles for the raft versions. I did not have luck printing the non raft version with only support. It would be okay to split the air nozzles off and print separately. Just glue them on with epoxy. About the blower, I found the Chinese cheap one would not handle the static pressure and did not work as well as a good blower. Buy it from TH3D.com or a reliable supplier. TH3D.com is a very good company and actually uses what they sell in their 3D Printers! If need be I'll print the ductwork for $25.00 plus shipping.
