Extensive modifications to existing machines may be necessary to accommodate it. Its meant to fit a 20mm aluminum t-slot. I am using t-slots from MakerSlide. 5 | 6 | Feel free to edit the source file. You must post edited files for all the use. 7 | 8 | OpenFeeder discussion can be found in the [OpenPNP google group](https://groups.google.com/forum/#!forum/openpnp). 9 | 10 | OpenFeeder was made with SketchUp 2013. Each part is on its own labeled layer. 11 | 12 | Current source version: OpenFeederRev7.skp 13 | 14 | 15 | # OVERVIEW: 16 | 17 | Key Features: 18 | * Simply made form .250″ acrylic sheet on a laser cutter (3d printable too). 19 | * Easily accessed and cheap components for the drive system. 20 | * Easily changed over to different size tapes, 8mm 10mm 12mm etc. 21 | * Adjustable tape height, from paper resistor tape to tape with electrolytic caps. 22 | * Designed to work with 20mm T-slot. 23 | * “Almost” infinite feeding distance. Able to feed tape form .05mm at a time to 12mm at a time. 24 | * Very smooth feeding, even at a very high speed. 25 | * Most likely over engineered! 26 | 27 | 28 | Basic Operation: 29 | * tapeAdvanceArm is pressed down, tape is advanced. The more the arm is pressed, the more the tape is advanced (vise versa). 30 | * Tape plastic cover is pulled backward with a small fishing weight. 31 | 32 | 33 | Advanced Operation: 34 | * Both the tapeGuide and the exitGuide are adjustable for paper tapes heights and embossed tapes heights. See examples in photos folder. 35 | * Wider tapes can be used by changing the tapeGuide width and the 8mm brass standoff height. 36 | * As tapeAdvanceArm is pressed, the one way bearing is locked in rotation, thus turning the tapeSprocket. Once the tapeAdvanceArm is released, the one way bearing un-locks and allows the arm to return to the ready position. 37 | 38 | 39 | # File List: 40 | 41 | * openfeederRev7.skp - Sketchup file of the entire feeder 42 | * tapeSprocket_FULL.skp - Drive sprocket w/ back spacer 43 | * tapeSprocket_Backer.skp - Sprocket back spacer ONLY 44 | * tapeGuide.stl - 3D printable tapeGuide part 45 | 46 | 47 | # BOM: 48 | 49 | **Laser Cut Parts:** 50 | * bodyLeft 51 | * bodyRight 52 | * exitGuide (two parts) 53 | * tapePresser 54 | * tapeAdvanceArm 55 | * washer 56 | 57 | (These parts can be 3D printed) 58 | 59 | **3D Printed Parts:** 60 | * tapeGuide 61 | 62 | (This part can be CNC milled) 63 | 64 | **Other Parts** 65 | * tapeSprocket 66 | 67 | (This part is tricky… should be cut from stainless steel.

Simply use a drop of dish soap in some water. DO NOT USE PETROLEUM BASED LUBE!! It will end up cracking the acrylic. 98 | 99 | 100 | More soon.... check the photos for more info. 101 | 102 | 103 | # WARNING: 104 | 105 | This is my very first ever 3D Cad design.
