@Gordon Graham It was introduced in Windows 10! I am Windows 11 but it should be in the same spot! Press Windows + I (i) Then go to System > Clipboard to turn it on!

@Lisa Graham Great idea, just to confirm, you would want to add loops to the lateral arm with the magnets on them but on the inside of the bracket? The file let's you customize all of these settings, it's a long list but it's powerful!! File Parameters Bracket Size - Vertical_Arm_Length / Horizontal_Arm_Length: arm lengths, 60–240 mm (defaults 200 / 220 mm) - Bar_Width / Bar_Depth: bar cross-section (default 20 × 12 mm, which grows automatically for large magnets) - Outer_Corner_Radius, Inner_Fillet_Radius: corner styling and strength - Edge_Chamfer: softens the top and bottom edges Hanger Loops - Loop_Count: 0–6 hanger points - Loop_Style: round eyelet, square tab, or a hole straight through the arm - Hole_Shape: circle for chain or S-hooks, slot for ribbon or straps - Hole_Diameter, Slot_Length: size the hole to fit your hardware - Loop_Placement: centred on the arm or measured from the tip - Loop_Spacing: centre-to-centre distance; match it to the holes in your sign - Loop_Center_Shift: nudges the centred group toward the tip or the corner - Loop_Drop, Loop_Wall, Loop_Thickness, Loop_Neck_Fillet: loop shape and strength - Loop_Alignment: where the loop sits through the bar's thickness. Bottom prints with no supports; centre and top need supports. Magnets - Magnet_Arm: vertical arm, horizontal arm, both, or none - Magnet_Face: outer edge (the side against the canopy leg) or the flat face - Magnet_Shape: round disc or rectangular block - Magnet_Diameter, Magnet_Block_Length, Magnet_Block_Width, Pocket_Depth: your magnet's size (defaults are for 25 × 5 mm round magnets) - Magnet_Clearance: extra room for glue (default 0.2 mm) - Magnets_Per_Arm, Magnet_End_Margin: how many magnets and how far they sit from the ends - Magnet_Wall: minimum plastic around each pocket - Magnet_Fit: thickens the whole bar, adds local pads at each magnet, or leaves the bar unchanged Strap Slots (optional)

@Lisa Graham Ahh yes I see what you mean! I can add that for sure! I also plan on adding some "addons" you can attached as "weights" to the bottom of your sign as well. Great thinking!

The biggest is whether it can go in your AMS. Standard TPU cannot be used in an AMS. It’s like trying to push a flimsy spaghetti noddle through a tube. You can ONLY use TPU for AMS in an AMS but the trade off is how firm it is. TPU comes in "shore hardness" and higher the number the harder it is. TPU for AMS is very hard and honestly I don’t find it very flexible at all; I’ve printed a Benchy with it. If you’re looking for flex, you want a lower number but you have to feed it manually through the external spool and through the TPU bypass in the back of your printer. You also cannot feed TPU through your standard PTFE tubes that feed to your tool head. There is a port on the back of your printer that will say TPU Inlet; you have to feed a PTFE tube through that and straight into the tool head. I don’t have an X2D so I can’t validate but here is some Bambu Wiki. https://wiki.bambulab.com/en/x2d/manual/tpu-printing-guide

@Gordon Graham Yea - Flow Calibrations can be tricky, I am terrible at the "Id this one better or is that one better" game. Flow is just 1 of the factors in printing as well, the challenge is if there is another factor ahead of it is off, calibrating the flow won't fix it. Are you using Bambu Lab filament? Standard 0.4mm nozzle? My initial thoughts are tempurature or speed; as I know @Lisa Graham said the filament has been sufficiently dried.

@Gordon Graham That one has fairly minimal stringing so I wouldn't worry about that; but this one does have some other flaws that can help pinpoint the issue; speed or temperature of the model during printing. You can see where the filament is dropping in spots it overhands, which is always a case of either not enough fan speed or too fast, or both. Are you printing from Bambu Studio or through the Bamby Handy app?
