XYZ positioning wall mounting for 2020 extrusion shelf

I am not so good in drilling holes in the wall, even with ruller and pensil ;), so I design this adjusted wall mounting. For my surprise, my shelf stands now like a rock, vibrations/oscilations of my MK3s reduced to minimum.

PETG and 100% infil are recommended. It is recomended 2 kits to mount at the middle and 2 kits to mount at the top of your shelf. I test 4 kits with 230*100*65cm 2020 extrusion shelf, working fine for last month.

Warning - check stability of your shelf, this mount is designed for not so much loads. If your shelf is going to fall down this mountings will not fix that.

How to use:

1. Assembly all parts according to visualization
2. Set all adjusting positions to the middle
3. Mount all kits to your shelf at final position
4. Mark point for wall drilling. Drill the wall, insert plugs.
5. Adjust mechanism “in air” it should tightly contact to the wall
6. Fix all of that with 2pcs of wall screw.
7. Adjust a little if it needed. Counter all mountings after.
8. If you need to adjust Y position some time later you could use provided parts (option - need 2 pcs).

Demonstration of adjusting

Bill of material:

• Screw M3*10 - 4pcs
• Screw M4*10 - 2pcs
• Screw M5*50 - 1pcs (length could be longer, depends on your case)
• Nut M5 - 3pcs
• T-nut M4 - 2pcs (metal strongly recomended)
• Nut M3 - 4pcs
• Washer M5 (d=10) - 3pcs
• Wall screw with plug - 2pcs (plug - 6*40 / wall screw d=3mm)
• (optional) Screw M3*16 - 2pcs
• (optional) Nut M3 - 2pcs

Benefits of design:

• Tested in real practice
• Optimal orientations already configured
• No supports needed
• No post processing
• Low weight / low price of production

As we talked before - stands like a rock ;)
