This is a milling head for worm gear hobbing, with tangencial method. ...It was reverse engineered from the two original drawings.

Jest to narzędzie do obróbki kół zębatych metodą obwiedniową./ It is a tool for machining gears by envelope method. ...Typ pliku:/File type: parasolid V21

On the CNC hobbing machine, it was observed that only some portion of the setup time could be reduced by separating and converting the internal operations to external operations. It did not provide the results expected, hence there was a need to...

hobbed gear

Have you ever had a very nice hobbed bolt that was cut slightly off the mark, making it impossible to use it with a standard big gear on your Greg Frost/Jonas Keuhling/Wade style extruder? This happened to me when I bought a very cleanly hobbed bolt...

A shaft for installing index gear of Hobbing Machine.

This is a M8 Hobbed gear jig I made. I design this on what I have on hand. Work perfect for me. You will need 2 608zz, 2 686 rs bearings and a M6 tap of course. You also need a #8-32 screw and nut for tension adjustment, I put a piece of metal...

... better than on the last MK8 which is a fail. The model is designed for 1.75mm filament which is actual standard. Anyway, the model is parametric, you can change variables in the Solidworks document to make a 2.85mm or any size you like hobbed gear.

This is a variant of http://www.thingiverse.com/thing:20850 It is intended to use a hobbed drive gear like this http://trinitylabs.com/products/hobbed-pulley There is a 608 8mm shaft and a 605 5mm shaft version. Instructions Assemble like the...

So i reverse engineered lawys mk8 and made it suit the smaller hobbed gear. Added a filament path while i was there too that used a random bit of PTFE tube that was 6mm in diameter. I used mdromans modified tension arm for the hobb goblin in this...

This is a V-Block to allow you to shim the filament hob gear on the main shaft to be perfectly concentric. Doing so will marginally improve Z layer stacking as per the research done by MirageC. https://youtu.be/c6JmCdovE0U The jig has two...

Instructions You will need: 1 x 5mm bolt and lock-nut 1 x MK7 hobbed gear 2 x 605 bearings 1 x 608 bearing 1 x 8mm rod of some sort 2 x springs 1 x M3 nut and set screw various other screws and nuts to taste ...in order to make this. It's really...

Model of a hobbed bush based on items bought on ebay to develop a new direct drive extruder. ...Fits a 5 mm dia shaft ( Nema 17 stepper) is 9mm dia x 11mm long Has a M3 hole for shaft grub screw Suited for 1.75mm filament

Small additions/changes to Joshua Payne's hobbed/bearing modification. X-Carriage is compatible with MK2.5 and the idler uses bearing like this: https://www.amazon.com/gp/product/B075CLMYRT/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 I cut down...

If you buy http://www.robotdigg.com/product/156 you will need this gear as the hobbed bit is not in the same location as the original design. ... I also recommend picking this up: http://www.robotdigg.com/product/135

Adding a damper to the extruder motor requires that the hobbed gear be moved up the shaft enough that there is no shaft left for most extruder knobs to grab. This knob grabs on to the hobbed gear instead. The notch in the end of the shaft goes over...

This is more or less a remix of http://www.thingiverse.com/thing:909259 but since the license is the way it is i had to post it as a new thing. The changes are bowden coupler hole enlarged and nut catch was added. Update bowden coupler hole enlarged...

Drawn per the mechanical drawings available from e3d. ...32 teeth

this is just to adapt the extruder cover to the modified extruder from https://www.thingiverse.com/thing:2261050

this gear was made so i can use my bolt that was hobbed at 26 mm from under the head. also included is a small gear with space for a nylock nut, and thicker walls. both of these are printed and do work. the gears are drop in replacements for...
