I can give it a try. I have a real Sterling to use for a test fit.

Check the outer diameter of your tube.

I have 3d printable parts for a PVC pipe build. They were created using actual parts.

I use PLA primarily. I use a Markforged printer at work that uses nylon. PLA does not give off an offensive odor like ABS. PETG is supposed to be a good material for strength. ABS and PETG work best with a heated bed. Matterhackers has some good information on different materials.

Praetorian blasters, The rubber blaster looks great. I was commenting on the photos of the deactivated sterling. My Sterling was cut up into pieces to be legally deactivated in the USA. It is illegal to make a functioning weapon out of the parts.I used the parts to make 3d models for printing replica parts on a 3D printer.

Your deactivated Sterling is more home made that a real sterling. Not even close. I have a real Sterling L2A3. Yours sort of looks like a Sterling but way too many differences. The front sight, barrel end, rear sight, charging handle, bolt opening, end cap mounting are all off just to mention a few. The magazine holder and front sight are definitely home made.

Check out my 3D parts in this link. http://www.whitearmor.net/forum/topic/31703-e-11-blaster-3d-printed-parts/ I have a stl file of the mag release button.

Acetone only works on ABS. It does not work on PLA.

Nice blaster. Looks like your springs are in the wrong way.

If you have access to a 3D printer you may want to try the parts I have designed for 3D printing. I used an actual Sterling L2A3 and measured the parts and created models in Solidworks. You may need to scale up or down to fit the inner diameter of your pipe. You can find the parts here: http://www.whitearmor.net/forum/topic/31703-e-11-blaster-3d-printed-parts

Do the holes in the front barrel section go straight thru from side to side or are they angled toward the center? Looks like they go straight thru.

Check out my thread for 3D printed E-11 blaster parts. I have a muzzle end for 40mm 1.25" pvc pipe. The models were created using a deactivated Sterling L2A3 i own along with a real M38A2 scope and Hengstler counter. The files are free and if you have access to a 3d printer you can have one in a short time or order from any online 3d printing service. http://www.whitearmor.net/forum/topic/31703-e-11-blaster-3d-printed-parts/

Look for Hecon Counter on ebay.

I am not in the business of supplying parts. You can use any online 3d printing service to order parts using the files I created. Some public libraries have 3d printers. Look for a local maker group. They may have a 3d printer.

I have a lot of stl files available for a pipe build. See http://www.whitearmor.net/forum/topic/31703-e-11-blaster-3d-printed-parts
