Take your multitool and cut out the marked area at the end of the pipe where the pellets should fall in. Smooth out the ends and the seams of the pipe so the auger bit can rotate freely.īefore cutting an opening into the pipe screw it tight onto the flange and mark the upper area and remove the barrel again. So exact measurement might not help you very much, but the pictures should give you an idea how it should be put together. The dimensions of the parts might differ from the ones you have access to. Moreover I have made a short video that should illustrate it as well. Now place the steel angle with the inserted rods at a distance to the barrel mount so that the auger's shaft sticks out for about 3-4cm (~1.5"-2"). So that no force is applied to the motors shaft. The coupling between the auger and the motor should always have a little clearance.
Because of its taper the auger's shaft pushes against the axial ballthrust bearing which itself pushes against the steel angle. It works like that: The auger pushed back due to its "backward" turning attitude. This is simply done by a sturdy steel angle and an axial ball thrust bearing.These ball bearing withstand alot of force applied to them. To counter that problem, we need a kickback protection.
In the worst case this could damage the worm drive inside the wiper motor. When the auger bit turns and hauls the pellets a lot of pressure builds up. 2x sockets (1 that fits on the auger bit and 1 that fits on the nuts of the motor shaft).3x Rocker (previously "rocket") switches.1x Axial ball thrust bearing ( Ebay) - Fitting exactly onto the auger bit's shaft.1x Faucet-mounted filter - 1/2" diameter.1x Water tap extension - 3/4" UNC threads - 1/2" German Inch - 50mm long, 27mm diameter (one core thread and one exterior thread).1x Fitting 3/4" US Inch UNC - 1/2" German Inch - 18cm long.1x Heating band (200 Watt 25mmx30mm) ( Ebay).ġx K-type thermocouple ( Ebay - like this one does not need to be that shop :) just an example) ->!!! Sometimes the PID is bundled with an SSR and an K-Type Thermocouple !!!1x SSR-25DA Solid State Relay 3-32V DC / 24-380V AC / 25A ( Ebay).1x PID Temperatur Controller - DC 12V version ( Ebay).1x Auger bit(diameter = 16mm length = 460mm).1x Wiper Motor (Ebay EU - 15€) / 5€ from the junkyard.So, let's say on a Saturday in your next workshop session you start at 10 AM and batten down the hatches at 5 PM you could make 4-5 kg of filament, saving between 125-150 $ leaving you with lots of filament for hundreds of thousands of eggcups and phone cases and other useless needful things.ĭepending on shipping and local prices, I would guess around 130-150$.Įxcept for the electronics everything listed here can be bought at your local hardware store.
(for 1,75mm filament using ABS/PC pellets). Using the build I describe here.roughly 1 hour. How long does it take to produce 1 kg of filament you may ask ? So how much money do I save when making my own filament ?ĭepending on the pellets you get you can make your filament starting at 1$/kg. Special greetings go out to Xabbax and his plain simple but super awesome Low Cost Filament Extruder ! Building at lower costs is the nature of DIY after all.Īnd much more fun than putting together a premade kit, of course. However if you are a fellow user the first thing that should come to your mind is "I can build this by myself.and cheaper.". And there was much rejoicing ! They have built plastic extruders everyone can build or buy at a decent price. Since the price for these filaments tend to top the actual material costs, printing before mentioned life savers is kind of expensive and could become a problem to the development of the ever growing 3D printer communityīUT FEAR NO MORE !! Some clever gents came along - Hugh Lyman with his Lyman Extruder may be mentioned here or the guys over at - and saved the day ! YAY. No ! You need plastic filament of course to print those super awesome coat hooks and wheel chocks. However, once you are a proud owner of a 3D printer you will soon realize that your wallet is far from being let alone. And with affordable I mean affordable like 200 $ and not "affordable" like 2.199$ affordable. Kickstarter campaigns like the one from QB-UP or M3D are popping up and they are finally "affordable". Make your own 3D printer filament ! Cheap and high quality at a decent speed of 150-190 IPM ! (4-5 meters per minute)ģD printers are cool and they finally start to drop in price.
