Nice, but I'm getting more and more leary of 3D printed aftermarket items. I bought a 3D stock for a Diana Bandit. It broke off during installation.
Rather than throw it away I epoxied it back on and drilled four holes to drive finish nails into it. Cut the head off the nails first to seat better.
I think it will be quite strong now.
Picked up my Beeman 1358 with a 3D printed moderator and it fell off. It had broken off where it threads onto the barrel.
I'd bought a 3D printed spare magazine holder for an Impact. It cracked horizontally the first magazine I put in it.
Losing faith in 3D stuff.
@pluric I saw this old post, but i thought I needed to chime in. There are many different plastics available for 3d printing. The most common plastic is called PLA, and in my opinion, is the least suitable for airguns. Also, there is a lot of tuning of the printer, and if the printer isn't dialed in right, it can have a really negative outcome on the prints strength. One of the issues with PLA is that if you dont print at a high enough temp or use inferior quality material, you can get poor layer strength as you have discovered. It also tends to be brittle, melt in direct sunlight, have poor water and solvent resistance.
I actually think 3d printing is revolutionary and truly amazing. Its also possible to make items with incredible strength and I have made such items. You have to know some basics about it and get items form someone with a good reputation. The machines and tuning process can be complicated to get right and not for someone who casually wants to print something. As a printer, you also have to know the physical properties of the materials and spec the right materials for the job.
