(Dremel) Turbine - Parkside Edition This is remixed from Landru's "Dremel Turbine" https://www.thingiverse.com/thing:13188 and ProfesionalHobbyist's "Dremel turbine (remix)" https://www.thingiverse.com/thing:3654472 I have a battery powered Parkside PFBS 12 B3 rotary tool. I thouhgt this device with such a blower could be very impressive. For example for cleaning computers. After I tested I can confirm it is good enough to inflate air mattress or inflatable boat too. Of course I have to make proper adapters first. But the main purpose is blowin out the dust from the computers. It is perfect for this. Technical details The Parkside tool has very different thread tha Dremel or dremel like devices. Therefore I replaced the thread in the mount part. The mount part is remixed from ProfesionalHobbyist's version. Also the shroud, which is unchanged. The collet nut of the Parkside tool looks generic. Its diameter is 10.5mm and it's 9.4mm wide between the two flat surfaces. I modified the impeller to fit to this collet nut. I took Landru's original impeller. This Parkside tool is (was) very noisy. Its stock bearing is poor quality I think. I replaced the bearing to a better one. But I saw this blower needs more stabilization. First I pushed in a 3mm diameter axle. Much better. But it could be more better. I bought 683ZZ bearing (3mm inner, 7mm outer diameter/3 mm height). I designed a bearing house with arms which fits to the shroud. It was easyier to print it separatedly, then attach with scerws, than print with the shroud in one piece. The screws are from old harddisks. I have tons of them. But any thread cutting screw with 2.5-3mm diameter could be good. The assembly Thanks to ProfesionalHobbyist the assembly is quick and easy. 1. Screw the mount on. 2. Insert a 3mm diameter collet in the rotary tool. 3. Screw the collet nut on, but not fully. 4. Push the impeller onto the collet nut. 5. Insert the 3mm axle. 6. With the impeller itself you can pull the nut tight. Keep in mind Parkside has a blocking button. So you don't need any tool for tighten the collet nut. This is why it works this way. 7. If it needs srcew back the mount a bit. There should be ca. or max. 1mm gap between the impeller and the mount. 8. Attach the shroud and click it tight into the mount. 9. Attach the bearing house (with the bearing in it) to the shroud with screws. These no longer need to be disassembled. So this step is required only at the first time. Printing It is not made for the world's fair. So I printed with 0.3 mm layer height. Except the impeller, which was printed with 0.2mm layer height. I set 1.2mm wall thickness (wall line count: 3). The thicker wall is better if post-production is required. I used 50% infill. I printed every part in horizontal position. I used supports everywhere. Except for the mount. The "tree" type supports were good for the shroud and the impeller. The line type (normal) supports for the bearing house. Bonus :-) Here are two reducers. Exactly for PC cleaning purpose. The bigger is good at maximum rpm. The smaller works good at half or lesser rpm. My favourite is the bigger with 14mm diameter. Print these in vertical position with supports!
