Is anyone interested in 3d printing a handle for 34401A?

That sucks.  All my 34401s came without handles and so all have the new reproductions.   

I think the HP design is OK but perhaps that is just relativism compared to my feelings about the handle on my Fluke 45.   I bought an NOS replacement for the Fluke 45 as it was broken and each time I have to pull it apart to adjust I'm convinced it's going to crack.  The HP handles are a way better execution of the same basic design.

This discussion got me pondering making something out of aluminum that telescopes apart at the center of the handle portion (under spring tension) avoiding the need to leverage the ends apart to adjust the position.

So...  I'm not trying to sell anything to anyone.   ;D

Few people know how to make a strong 3d printed part.  A well printed piece will have nearly full material strength in the X and Y axis and approximately 50% in the Z (layer adhesion).  With annealing, a 3d print can be nearly as strong as an injection molded part in all directions.  Yes, I understand there are minor shrinkage/expansion issues to deal with, as caused by annealing.  And then there is the slicing approach to reinforce the pins.  I'm pretty confident it can be done but I will print one and use it for a while as an experiment, if nothing else.  I'll report back but not for a few weeks so I can test a couple of parts to failure, etc.

The point being, this isn't for 12 year olds who only know how to print cosplay accessories.  It's for people who understand 3d printing and enjoy printing the things in their lives.  It wouldn't surprise me if no one is interested in this micro-project.  That is no problem.

Please accept my most heartfelt wish for a wonderful evening.   8)

My suggestion. "Put up or shut up".  There is ZERO engineering information in your first post or any since. Just a CAD image that looks like the HP handle.

Oh my.   If you can be less condescending in your tone I think this discussion will be more productive.

Mine just broke adjusting the position.

Seriously, its like comparing a tug boat hoist to a 1 inch tow strap from harbor freight, best case, used to secure a BMW

I've printed the dog connector and it fits my 34401A perfectly but I haven't printed the entire handle to sweeten the fit.  It isn't something I've needed.

If someone is interested, I will hone the design and upload it to Thingiverse (or similar site) as an open source part to share with the community.  My meter doesn't have a handle so this was a clean sheet design.

Notice, it will require heavy support to print FDM and I suspect it will be more problematic to print in resin.  Still, filament isn't all that expensive.  It should *just* fit into the built space of my resin printer but it won't be an easy print there, either.
