    Limit Support to Certain Areas?

    Hi, I am making a "holder" for a small USB hub. It is the shape of a rectangular frame - where the USB hub will "slide into it" in slots in the side of the frame - see pics. I want to limit where the support is. For example - somehow tell the slicer to only put support in this or that area, and not in other areas? (the holder will sit under or on the underside of a guitar pedalboard; which is why a holder is needed) I am using Bamboo slicer (mostly because my printer is a Bamboo and I can wirelessly send the file over to print)...... I am open to another slicer. When I check the "support" checkbox.... the entire area, the empty center area AND the slots in the side of the frame shape get supports. It's way too hard to clean out the supports in the slot area on the sides. See the pics. Any thoughts on restricting the support? TIA, AJ

    Prusa Slicer has support blockers that can be added to the build plate to accomplish what you seek.

    Another way to approach it is to attempt to convert those areas with large volumes of support to bridging. It's challenging to determine from the images provided where this would be done. If you place a flat panel of 0.4 to 0.8 mm thickness (one to two nozzle widths) over the area in which the supports would be clustered, the panel becomes one side of a bridge and eliminates the supports completely.

    Check out Maker's Muse for some methods:

    I am confused.. looks to me if you put the far side to the left when looking at the second picture on the build plate no support would be needed..
    In other words, where the arrows point in picture2 would be facing up. in that orientation I don't see anything over hanging unless it is on the side I can not see. You always want to position the part with the least amount of over hang.
