extruder idler prusa 3d models

It is to adjust the spring tension of the extruder idler for Prusa i3 MK2(S). Prusa says spring should be circa 13mm long. This spacer is 14mm height as I prefer less tension. You tell your slicer to shrink or expand the spacer according to your...

I change quite often the pressure on the idler then I designed scroll wheels to avoid the use of the allen key. It is quicker for me. ... You need M3x40 hex (ISO4017) screws instead of the ISO4762 M3x40 screws.

Printing was possible, probably thanks to the friction the filament has just touching the extruder gear, but most of the time the extruder had difficulties loading and unloading filament as well as under-extruding.While waiting for the missing parts...

The little plug on the idler door of the extruder was annoying to remove - so I added a little handle or "tab" to the top of it to make taking it out and putting it back in easier. I also made it more curved and nicer looking! ... MUST BE PRINTED...

This mod replaces one of the Bondtech idler gears with an MR685ZZ bearing, without the need to modify any other parts of the extruder body. It also requires a 5x25mm stainless steel shaft, but I suppose you could print one instead. I prefer the...

Edited mk3 extruder for possible ussage of mk2 gear feeder and bearing. ...For me the 1mm High version worked best.

I usually found myself in an uncombortable situation while changing my filament, The extruder idler is kind of sharp where you have to rest your finger. ...Thats why I remixed it to be smoother, also added a piece over wich you can rest your index...

The reason I made a derivative, is that the filament guide hole I was uncertain having it clamped between the idler and the main extruder body would work correctly, as I don't have my printer built to make these to try. ...The 3d model of the springs...

This is the exact Prusa i3 MK3S MMU2S extruder idler with one layer added to the part at the top that breaks the filament sensor beam. I modified this piece because I was attempting to pair PETG and a Flex filament. I found that the Flex filament...

In my experience, depending on the quality of the filament, every 2000-4000 filament changes it is necessary to remove debris and filament dust in order to have the Prusa working properly. In this iteration of the idler door the gap between the...

In this iteration of the idler door the gap between the housing and the idler door is increased, hence the possibility of some self-cleaning mechanism increased (increased, not solved). No negative effects were experienced so far. Debris falling...

This was remixed from the original Prusa part, my original one broke at the top where the lever part comes out. So I have filleted it around the top where it broke and also made the lever a little bit longer. It is now much stronger :) When...

... added a cap for the screw heads. Now the idler handling is really easy. Place the screws to the holes of the printed cap. The holes are designed to fit tight with the screws. Then place the springs and screw the idler to the extruder body. ...

This mod that altered the idler door to include a small M2x10mm cap screw through the lever that triggers the IR sensor. This enables you to fine tune the trigger by moving the screw in or out.</p> <p>I decided to create a mashup of the two of these,...

if making a prusa mk 2 dolly clone like in toms videos on youtube you will need to print one of these to use as an axel for the prusa idler bearing. its a 5/16 rod. the stl has three small pins with slightly differences in tolerance for you 3d...

The idler arm, just wasn't long enough to reach the IR sensor. ... So I made the arm 0.5mm longer, and that was enough.

remixed to reinforce the area where the screw is inserted. ...the original wouldn't print with my 0.6 nozzle and i didnt want to change it

This is based on the Prusa MK3 updated R3 (August 3, 2018) Extruder and has: - 40x40x20mm Fan mounted without losing print volume - Cooler Heatsink of Hotend due to improved airflow and more pressure - Cooler extruder motor as some air flows into the...

Stronger thin section of extruder idler for Prusa i3.

I used this part to repair a broken Extruder Idler for my RepRap Mendel 3D Printer. ...Also, I did an extra level to prevent it to broken again.
