- x6 M3 Studding bolts 70mm long at least The important area with screw it’s the end -x8 M3 15mm For the hangar bay assembly. You could use glue too I suppose... - x4 40x40x10 Fans 24V Connect them in parallel to the FAN PWM - Check mA so it’s never higher than 400-500mA - An Ultimaker Original Plus On UMO (not plus) you should design an area to hold the Thermocouple Transmitter - M3 TAP To process the Aluminium laser cut part for the m3 holes. You could also use m3 screws to make the ‘screw’ but I don’t recommend that. - M3 Drill and M10 Drill To process some 3D printed parts. 10mm drill isn’t a must, you can just clean the hole of the fan cap by hand, but I prefer a clean 10mm hole. - Needle Nails To clean up some of the magnet holder holes. - x6 4,4mm dia springs 5mm springs should work too. Also you can use pen springs can work. I used 3 pens and did cut the springs in half. This works, but the spring will end up going through the washers or the wood and will make alignment a real pain. - x12 m3 Washers To isolate the springs so they don’t go through the wood/printed part - x12 10.0 x 5.5 x 2.0 mm N45SH The ‘SH’ grade means it won’t loose any strength unless it reach 150C. Each has 1kilo strength. Never use N50 or higher, they will lose strength at 60C. Better safe than sorry. - Araldite Crystal That’s what I used. You can google for glue’s for neodymium magnets and use the one you prefer. Read all the safety instructions and info before using it.
