Filter panel for blaster cabinet media return. It should keep those large chunks of paint or other items that can come off in blasting.

My cabinet is the 62144 model. My long wall angles 62.5 off horizontal (27.5 off vertical} and the short wall is 46.5 off horizontal (43.5 off vertical). I angled the panels 5 degrees wider to support the desire for the top edge to engage first.

I started with a metal 3mm Mesh plate, but those thin paint chunks would usually turn sideways and some point and slip through little gaps along the plate. Even though the paint would accumulate on the plate, a good blast of air by the gun in motion would make it fly about. A cut plate really needs to be formed to the inconsistencies in the cabinet funnel surfaces.

This is Functional for cabinets converted to bottom media return and use a low media reservoir model. The TPU is angled back to engage the funnel walls.

This print requires TPU / FLEX filament for the frame. You can insert your own filter frame or add a printed one. 3mm mesh frame provided.

Version 3 opens the corners more so the media flows in and sits on top to cut down on lifting the flaps on the approach. Some media is allowed to pass under the corners.

Print options:

Print Option 1:

• Print the frame and the plate separately.
• The frame should be printed in TPU/ flex.
  • The 1mm thick PETG plate tends to be flexible and you may want to bond it to the flex. CPVC cement being my favorite for PETG to other surfaces. Other materials may not flex as much. My cabinet is sometimes by the garage door and the local sun would heat the box and turn the PLA into putty.
  • There is a 2mm thick plate to reduce flex. The hole in the center is so you can add your own knob. The hole was added as the plate prints upside down.

Print Option 2:

• Print the all-in-one with the first layers up to the main plate surface being in PETG or material of your choice and the layers for the framed HEX and sides being printed in FLEX / TPU.
  • If you are multi-material you can mix filaments as much as you want, but likely the two layer types will be just fine.
  • Remember to adjust your heat just before the media change to a good crossover temp where both materials will still bond.
  • Adjust your retraction and travel rates to be appropriate for TPU if your printer requires.
    After your first new media layer make sure your temp is in a very friendly range for the TPU / FLEX you are using.
  • This option has a 3mm hard plate. It sits lower than then two piece as I adapted the flex frame I had already designed to make this.
    The skirt HEX overlay is to add bonding surface for the flex to reduce pull that may separate it.

Let me know if there should be a larger mesh options.

Also keep in mind there is enough variations of the box and the play in assembly we may find some boxes have different proportions. Ether size it with a plate or cut some cardboard in the plate size. If we need to create some other dimensions let me know.
