Skadis Low Profile Mounts & Connectors

This is a collection of Ikea Skadis board mounts and connectors intended to simplify mounting and alignment of multi-board installations.

Feature Summary:

• low profile - 10mm vs standard 17mm.
• minimal slot use - one slot per location with integrated board fastener.
• integrated wall mounting - counter sunk holes for #8 mounting screws. 
• flexibile placement - can be used in many slot locations.
• additional support - add a board support or wall mounting screw anywhere in your Skadis array.

The concept is loosely based on @Bouli_599629's Ikea SKÅDIS (Skadis) board connect. Thank you for the inspiration!

Printing recommendations:

• PETG or other durable material
• 0.4mm nozzle
• 20-25% infill
• thin wall detection
• arachne wall generator

Marking pin:

I designed a small marking pin to help with installation. The idea is to get a mount or two going the hard way, then use the Skadis board to help find the next mounting location. To use the pin:

1. Put the mounting block you want to use onto the back of a partially mounted Skadis board.
2. Insert the marking pin into the wall mounting hole, pointy side to the wall
3. Give the board a good tap against the wall from the front. This should leave a little dimple where your next screw should go.
4. Remove the pin and the board. 
5. proceed with drilling or screwing as needed.

Pins didn't last long and were easily lost for me, so you may want to print some spares.

Wall mounting holes were designed for #8 flat head screws. I left extra clearance for #10 screws but I found fit depends on the actual screw used. Screws must be flush or below the surface to avoid interference with the Skadis board. I used 2" screws to work with wall anchors.

Known issues:

1. Thin walls around screw-in-tab design. Walls may be omitted at the side of screw holes in the slicer, if not configured correctly. This is the reason for the thin wall detection and arachne wall generator recommendation. I suggest having a close look at what your slicer is doing in these areas.
2. Threaded holes do not print properly. I never got the M4 screw holes to print well enough to use as-is. I had to use a tap to thread the holes, which worked quite well. I chose not to use a threaded insert in this case to get more thread contact throughout the entire  depth of the tab/slot features. Stock board mounting screws are M4 x 15mm, which thread the full depth of the mounts, as designed. 
3. Wall clearance. No problems found here yet but it is worth noting Ikea left 7mm more space to the wall than I did. All accessories seem to fit fine so far and I think I have tried them all. If you find any issues please let me know.
4. Novice CAD. I'm really new to Fusion360. While I think the designs are fine, the models are not parametric or otherwise fancy. No mesh, just good old solid models. If you find any issues please let me know. 

Pictures are limited at the moment. I will post more later if possible.

Hopefully you find these parts as useful as I did. Enjoy!

Organized models into folders by file type.
