Now that you have fabricated each element of the fermenter, it is time to assemble it! Below you will find the assembly strategy. Gather the different elements and bring your Allen key and the bolts and nuts referred to above. Please also refer to the CNC cutting file for the names of the different parts of the enclosure.
First, prepare and place the inserts and magnets
- Push a nut into each 3D printed insert, there are seventeen in total.
- Insert a dot of white glue into the seventeen 4mm pockets on the ‘back’ and ‘top’ parts.
- Then push the inserts into these pockets, with the visible part of the nut facing downwards. In other words, the nut is not visible once it is in place.
- Repeat this action for the two power inserts that are to be inserted into the two ears of the power pocket on the ‘back’ part.
- Next, insert two dots of white glue into the two 6mm pockets on the ‘top’ part
- Take the two 3D printed magnet holders and insert the square part into the pocket, the protruding part towards the inside.
- Then insert the magnets into them, paying attention to the orientation of the poles.
- And finally, insert the two other magnets into the two 8mm pockets of the ‘door’ part paying attention careful to align the poles.
Second, attach the fan to the “top” part of the enclosure
- Lay the ‘top’ part flat on your work surface with the slots and pockets facing upwards
- Place four 40 mm bolts with four 10 mm spacers on the Fan. Screw the PCB into its nuts inside the ‘top’ part.
Thirdly, insert the “back” part into the “top” part and attach the PCB
- Lay the ‘back’ part flat on your work surface. Insert the top part into the top slot. Make sure it is aligned correctly before pushing to the end.
- Place three 15 mm bolts with three 10 mm spacers on the PCB. Screw the PCB into its nuts inside the top part, inserting the knob and screen into their holes.
- Connect the fan to the PCB (air).
Fourthly, attach the heating pad to the “back” part and insert the “bottom” part
- Prepare two sets of 2 x 10mm bolts with 2 x heating pad holders and 2 x 5mm spacers. Screw the two sets on the inner inserts of the ‘back’ part. Before tightening, place the heating pad between the heating pad holders.
- Connect the heating pad to the PCB (heat).
- Insert the ‘bottom’ part into the bottom slot. Make sure it is aligned correctly before pushing to the end.
Fifthly, attach the power
- Turn your unit 90°. Insert the power button inside the power holder and screw it into the inner slot of the back part with two 10mm bolts. Connect the power button to the PCB (power).
Sixthly, attach the sensor and the technical panel
- Screw the sensor holder to the technical panel with 2 x 10 mm bolts.
- Connect the sensor to the PCB (sensor). Insert the sensor through the slot in the technical panel and slide it into the sensor holder.
- Screw the technical panel to the ‘top’ part with 2 x 40 mm bolts and 2 x 35 mm spacers. As well as to the ‘back’ part with 4 x 20 mm bolts and 4 x 15 mm spacers.
Finally, close the enclosure with the sides, the front foot and the door
- Inserts the dowels in all the holes of ‘side A’ and ‘side B’ parts
- Insert the unit inside the ‘side A’ part into the slots. Make sure it is aligned correctly before pushing to the end.
- Insert the unit inside the ‘side B’ part into the slots. Make sure it is aligned correctly before pushing to the end.
- Insert the front foot from the bottom
- Insert the door from the top
- If the bolt turns loosely, reduce the size of the spacer by cutting 1 mm off one end with a cutter.
