You have to clue the front and back together. So you can use a higher density for the back.
About my pegboard:
I have buyed a pegboard from OBI (
This pegboard has square perforations with 1cm^2. This squares has the advantage for us owner of 3d printers that you can build your own set of items directly out of the printer.
The normal pegboards are only drilled with 3mm holes, so you need metal hooks because the prints will break with that thickness.
I am offering a series of all my prints for this pegboard for using or inspiration of your own items.
Please think about the needed density of your prints when you are slicing!
i have used PLA with a density between 25 and 50% (often with support, some items you have to clue befor using them). A resolution of 0.2 mm should be enough for your pegboard-items.
