B&T SPC9 Magwell updated to version 0.6

Magwell fits B&T SPC9, APC9, GHM9 lowers which takes B&T magazines.

Every element is printed in the strongest orientation to wait stand the forces. Model needs to flex do not go crazy with infill and parameters.

Shape helps to bump lock on covers.

Install on  rifle:

1.  Push slides to rear element

2.  Slide front to lower

3.  Slide rear to lower

4.  Push rear into front keeping alignment

5.  Use rubber hammer or magazine to bump front to rear.

Change log:

Improved strength by rounding critical sections. (not all printers my handle overhangs at rear part)
Improved print speed and overhangs in front section
Optimization for faster printing.
 

Testing:

Printer: Voron0
Slicer: Orca
Material: Prusament ASA
Print was few minutes faster with noticeable quality improvement.

Print settings:

Global setting
Layer 0.2
perimeters: 4
infill: 15%

Snaps:
Layer 0.1
perimeters: 6

spc-9-magwell-front
Check image of seam position.

Material: Prusament ASA

Prusa MK4S:
Use 3mf file and print in given plate order. Start print when enclosure reaches at least 32C.
Before printing use califlower or other model to calculate “shrinking compensation XY”
Material: Prusament ASA (Magigo glue might be necessary)

Voron printers/Prusa Core One chamber temperature starts at 40C (best possible results)
Other printers bare minimum is 32C and experimenting with print speed/fan speed might be required to balance overhangs and wrapping. 

Please keep in mind that any material might be used but due to outdoor summer temperature and UV light ASA is the best pick.

Please use print profiles if possible. 
 

Print info old version (0.4):

Please follow optimal print orientation image (everything on one plate).

Layer 0.2
perimeters: 2 (max 3 but its very stiff and harder to mount)

spc-9-magwell-front
20% honeycomb

spc-9-magwell-rear
20% honeycomb
layer: 18-27.2
Infill 100%

snap-left and snap-right
infill 100%

Required for mini
Avoid crossing walls enabled
Seam positions nearest
Fill gaps enabled
Top solid layers 6
combine infill 3

Required for mk4:
max volumetric volume 12mm3/s
max crossing infill speed 0
fan speed min and max 10%
infill 140
solid infill 200
top solid infill 1000

If layer low then 0.2 its very easy to damage guiding walls with magazine/bullets, perimeters have to be change to compensate
Perimeters: 3 or more
Extra parameters if needed enabled

For Prusa printers:

Model was design to be printed on Prusa mini+ with revo and bondtech extruder and stock mk4. 
Tolerances are set for Prusament ASA stock profile minimal chamber temperature to start print is 32C, preferable more then 36C. 
 

Other printers:

Tolerances are set for Prusament ASA stock which in my case model is 100.7%(XY) bigger then it should be.
For Voron0 scale factor should be around 0.972 (100.4% shrinking in my case, 100.4/100.7=0.972).
 

FAQ:

• Weak bonding will result sheering in rear element left/right corner above product information (spc-9-magwell-rear) after few months of use.
   

• Custom graphic on sides, yes its possible and does not break product strength.

• Commercial usage, yes if we agree on price, then access to f3d files will be also possible.

• Image presents 800 loads and 3000 suppressed shoots in course of summer, offspring and winter.

• Washing in ultrasonic cleaner when on rifle is forbidden for version 0.4.
  Washing in ultrasonic cleaner when on rifle is not recommended for version 0.6.
