ASA smoother

For completing devices you need:

• 12V 80 mm PC BRUSHLESS fan (80x80x25, or 80x80x10.8)
• glass container with outer diameter 148 mm and min. height 190 mm (I use glass vase from Pepco, SKU 35327801)
• 4x M3 screw (lenght 6-10 mm) + screw tap for creating a thread or threaded inserts M3
• 4x M4 screw (lenght 6-15 mm) + screw tap for creating a thread
• DC power coaxial connector (for low voltages) to the panel; socket; 5.5/2.5 mm (for example GME.cz 806-459) - optional
• glue for plastic and universal glue
• DC voltage source 7,5-12 V (min 500 mA)

Completing the devices:

1. print all parts from PLA or PETG; main setup: 3 perimeters, 20 % infill, 0,2 mm layer height
2. use Height range modifier for the main body: 1-21 mm, solid layers top and bottom 0, 0 bottom solid layer for the rest of the body; 20 % gyroid infill - this is IMPORTANT for proper air flow from fan (according the pictures)
3. use a brim for legs
4. glue the handle to the cover
5. glue the base on the glass container (optional)
6. install the DC power connector to the top-ring (optional)
7. make M3 threads in all legs (or use threaded inserts M3 - you have to drill bigger holes in the legs - according to M3 insterts)
8. make M4 threads in the main body (for the fan)
9. install all legs on the top-ring by M3 screws
10. glue legs on the main body (for centering use the cutouts in the main body)
11. install fan on the main body by M4 screws (position the fan wire against the connector on the top-ring)
12. fix the fan wire on the leg (use the heat shrink tube or cable ties)
13. solder the wire to the connector (red wire to the center pin) - optional, or you can use your solution to power the fan

Instruction for using:

• Be careful, acetone is highly flammable
• Work only in well-ventilated areas

1. place the ASA model on the main body grid (or you can use hanging eyes on the bottom of the cover)
2. pour acetone into the glass container (to the aproxmatelly 4 mm height) - WARNING - the acetone level must be at a sufficient distance below the fan (approx. 5 mm)
3. connect power to the fan/connector (or connect the power directly to fan)
4. insert the complete with ASA model to the glass container (use the cover)
5. wait for the smoothing :) Smoothing time depends on experience - approximately around 30 minutes
6. check the smoothing process (acetone level, model smoothing)
7. disconnect the power of the wall plug
8. carefully remove the ASA model from the glass container
9. leave the ASA model on the well-ventilated area for a several hours
10. pour the remaining acetone from glass container into the original tin container
11. ventilate the glass container and equipment well

Upgrades in version Evo1 (2024/08):

• thicker walls of the main body
• the cutouts in the main body for legs centering
• higher top-ring
• 4 pieces thread holes for fan mounting (2 holes in version zero)
• bottom hem of the main body
