Leshiy 2 - 3D print

Jump to latest Follow Reply
I made the original design in 3 parts for the ease of loading the pellets head first, this version will save material and printing time for the cost of having to load the pellet backward - maybe I will design and post a speedloader for the speedloader later


And the flat upper surface made it possible to imprint the Caliber and name of this very fine Forum (thank you Michael and Moderators!)

Original description recycled:
designed as simple as possible, you will only need the 3 2 printed parts, one 4 mm x 30 4 mm x 22 screw with counter sunk head, a shim and a lock nut (or 4 mm nut + blue Locktite)

The discs is held i position by friction between the printed parts, the lock nut is used to adjust this friction, no balls and springs

Ad glue to the head of the screw, this will make it stick to the adapter part

Put the parts together, tighten the nut and let the glue settle, when dried, loosen the nut, adjust for friction

The speed loader is fixed by the L2 indexing arm, only one hand needed load, turn clockwise to drop the pellets in mag

Changes to print settings:
The 4 indexing arm is higher than the base, ad extra cooling at the last part of the print, with my print at layer hight 0.24 that be at layer 53, so my fan settings is 60% from layer 2 and 100% at layer 53

Be kind, print and share with those poor souls that do not own a 3D printer :)

Edit: .20 cal version added

You guys with printing capacity could make a new topic, something like a "3d printing Hubs", a place to find a local or at least in same country 3D printer owner willing to print and post (for a price of cause), but its really not up to me to start a thread like that as I do not have the time to offer this service

Would link to it of cause, so would others with free air gun related designs

Brilliant to see someone releasing the files for one of these, thanks. Could you please do a 0.20 version of this if possible/ not to much trouble.

Was thinking about making a .20 cal version but..

In my experience the average 3D printer do not size small holes very well - chances are you will find more variance in hole size in the range of 0-8 mm between different 3D printers than the difference between .20 and .22 cal - with small holes, best practice is to make a test print and adjust to specific printer (and printer settings) - and BTW was the reason I in printer settings wrote "outer perimeter first" (that be inner parameter for holes), to lower those variables

So while designing this, a lot of head scratching was going on in trying to quantify the average hole size fault of 3D printers but I hope I got it about right

Bottom line is I think the .22 model will work just fine in .20 cal, a pointed or round nose pellet will find its way home

But if not, just let me know and I will make a .20 cal version no problem!

BTW, the hole dimensions, shared by the 3 and 2 disc versions is:

0,177 cal (4,495mm) 5,50mm

0,22 cal (5,588mm) 6,50mm

0,25 cal (6,35mm) 7,35mm

0,30 cal (7,62mm) 8,50mm

Thanks Towle, I'll give the .22 one a go today.

I use Cura and it does seem to undersize holes by about 0.1 to 0.2mm despite everything else being calibrated spot on. I've been using the 'hole horizontal expansion' setting in Cura to adjust hole sizes. For single holes it works well but not sure if its meant for multiple holes, but I'll give it a try and see.

I would expect the expansion settings to work for all through going holes

I made a .20 cal version of both models, you will find them in the original but edited post, but as said I think the .22 cal will work just fine for you, its only 0.5mm diff.

Also made a test plate to test the pellet size against, listed with calibers and hole sizes same as the speed loader models

Att mod: I just posted a message and used half an hour to edit and post another one, hitting the submit bottom it all disappeared, I have no time for this, so here's the file only, you will have to figure this out yourself - I suggest you adjust the time limit for postings on this forum
