Broken Plastic Parts

Good afternoon all,

So I am working on my M4 again and as I have it apart, I can’t help but notice 4 broken parts:
both of the little inverted wedge pieces that pull the collar tight against the router, as are both of the support columns that have the bearings inserted in them.

So are these parts able to be made with PLA? or do I need to wait for replacements?
The columns I think I will just superglue and then reinforce with electrical tape. But the inverted wedges are not so simple.
Thank you,

Have a look at

There are a number of parts ready to print. Recommend the Turtle Clamp.

Also my alternative inner support (need longer bolts), prints without supports, shorter so need to replace all 4. Only 2 spacers needed.

Ian,

Thank you for sending those. Today I started printing the supports, spacers, as well as a pair of turtle clamps. I’m looking forward to assembling this once my hardware order comes in.
This is quite the community that has been built!

Thank you again for sending those,

I have the same problem with my clamp wedge. both of them are broken after just a couple of hour cutting. I just placed an ordered of some new ones. but to 3D print would be a good substitute.

@bar I seams like they broke from the same place. The crack starts from the same corner. perhaps a bad batch. Or a redesign with an added 45 deg broken egde to remove the sharp 90 deg edge would make it stronger.

the clamp wedges are known to be weak. There is a 3d printed design posted (in
the router-b-gone thread if not elsewhere) and a far better clamp design posted
as a turtle clamp

Dan,

I 3D printing a couple of these clips to get moving again, but ultimately the Turtleback design is what I settled on. I really like how much more stable the router is held.
The only drawback I have had is that I needed to print new stands, internal support sleaves, and had to get longer screws.
Good luck,

That is good to know. I will have that as a fallback solution.
