Three Maxim inspired short, fat LDCs: .177 / .22 / .25

Did you set up some kind of enclosure for printing ABS? The temperature and fume issues have kept me away from it. I'm curious what you or others are doing for it.

i'm using overture abs and sitting right next to printer hardly smell any thing. i'm in a small room 77degrees 40% humidity.

It was just meant as a caution, everyone's sensitivity is different. Melting plastic is an industrial process and it releases chemicals, kind of like using solvents . ABS just happens to be one of the nastier ones. Plenty of information out there.

everything you posted was correct, had researched the smell factor beforehand a couple days ago. i was pleasantly surprised this stuff don't have a toxic smell.

I just want to echo WhatUPSbox?'s concern here.  Just because it doesn't smell, or smell bad, doesn't mean it is not spewing toxic fumes. 

I've also avoided ABS for the same reasons -- need for an enclosure to maintain temp, and to contain/vent fumes.  And ideally to relocate control boards to outside of the enclosure as much as possible to avoid cooking them.  For similar reasons, I've avoided resin printing as well.  They will be vented, or I won't be printing them.

has anyone made any of the maxim short fat ldc?  I've did a conical and version with a spacer on the threaded end and a mutant ldc.

Nifty, Mike!

Could you please repost the STL files?
I really want to try them.
I will update here on the results.

John,

The files are huge.  Could you please be very specific about which of the many variants you are interested in; including caliber, OD; and monolithic or segmented?

[naptemp]

I am interested in:
-.177 and .22 calibers
-not sure about the OD (the quieter the better for me)
-segmented preferably, also the monolithic if you have room

Thank you

John,

I have combined all my Maxim zip files into large zip file.  You will need to sort through the contents to find which you want.  The file names are descriptive.  If an individual file seems missing, PM me and I will look for it.

I am OK sharing the files, but I am not OK spending hours identify each file to decide if it is one you want or not.  You will see that there are dozens of files...

The ZIP file containing the smaller ZIPs can be downloaded from this wetransfer link for 7 days:
https://we.tl/t-ma41oUgFd3

Each smaller ZIP file contains logically associated files.


EDIT:
While you are at it, the extended Notos design I did should perform almost as well as the Maxim designs.  This, while being 32 mm rather than 50 mm in diameter, but twice the length.  Also, the Maxim designs use about  three times the material to print. 

So, evaluating the extended Notos design against the Maxim designs for performance would be appreciated.  Here is the link to download the Notos extended STL: 
https://www.gatewaytoairguns.org/GTA/index.php?action=dlattach;topic=208202.0;attach=434349

Printing notes:
Note that all of these parts need to be printed standing on their front face (threaded end up), bore axis vertical; with supports turned off.  Failure to print in the correct orientation will produce a scrap part.  Ditto, if you print with supports turned on - because the supports will be trapped inside, and be unremovable. 

You can print at less than 100% infill, but then need to set the wall layer count up to 3 or 4, so the baffle walls are solid where they are thin.  The Maxim designs can be weight reduced by using 20% infill, with a 4 or 5 layer wall count because the curved shapes inside create a lot of areas with very thick walls.

Thank you for the files.
I am downloading the now.

I also printed your Notos insert and it works well.

Would you be willing to repost the zip file please? I would love to compare with the extended Notos design I have on my ~35fpe gun in 22, and also print one for my ~70fpe 25 cal.

I will search for the thread talking about measurement techniques so I get some objective data.

Thank you, Subscriber. I read the whole thread again to figure out what the files are. The file dates help a lot in seeing the progression of the designs! I picked the 2x4 inch monolithic and just kicked off a print. In 7h52 I'll know how it turned out!

[subscriber]

Dino,

I am glad that you could decipher the file dates.  A am generating so many designs for different platforms that my mental RAM is full.  If someone asked me to explain all the files after the fact, that would be many hours of work.  I would rather move forward

Anyway to get this file of all 3 again? Loved your P-rod and M-Rod ones and came in handy.
Thank You

Please be specific about which part files you want.  Do you mean the short, fat Maxim inspired LDCs?  In what caliber?

There may be better moderators for your application, based on weight and performance.  What is you application?
