Center piece of Bertho's Extruder Upgrade

Recommended Posts

Hello,

I did something really dumb. Darwin awards dumb...

I cleaned my shop shortly after getting my printer running well with the Bertho's extruder upgrade. I was so confident that I threw away the pieces that it replaced. When I made it, I couldn't find the M3X50mm bolts anywhere, so I just ABS glued in some 4-40 threaded rod. You can guess the outcome here: the threaded rod pulled out.

Can someone print me up the center piece for the Bertho's extruder along with the right size screw and spring? I think mine broke because I was overtightening it due to the spring I used having too low of a spring force.

An easy $15 for the printed part, the screw, and the spring. I really don't care what color or material you use.

-Matt

I got some that were like M3x60 with a smooth shaft at the RCA helicopter shop here. Had to buy a bunch so I could probably send you one if you needed it still. Mine are cap heads though, so they wouldn't be exact copies. I got mine to work with a bit of a combination of the Bertho bearing plate and the UM design.

I know this is an old topic but I figured I'd put it out there. I recently made this extruder upgrade, and after a LOT of searching at local stores, I found everything I needed at Sears Hardware. 50mm bolts, springs, washers, and nuts. I felt so stupid buying screws off the internet so I didn't give up looking around town. $4.64 was my total price, cheaper than just the shipping from McMaster Carr!

    • Architect Design Contest | People
      The goal of this contest is to design a set of people figurines that could be used in such a project to make an area, office or mall seem populated. 
      Think of different types of people in different environments, like walking people, people standing still, working people, and both men and women.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
