Skylark v1.0 150: Bow tie clearance clash on Floor End blocks

Hi WikiHouse Community,

I’m reaching out from Spain to introduce myself and bring a design issue to your attention. I’ve been a long-time follower of WikiHouse, having manufactured both standard blocks and custom XL/XXL variants for previous projects. I’m glad to finally join the forum!

While preparing CNC files for a new project using the Skylark v1.0 150 series, I encountered a physical clash that appears across all three Floor End blocks in the library:

  • Zero clearance for insertion: There is no physical room to slide in the internal bow ties that connect the inner face of the “Wall” blocks to the “Floor End” blocks.

  • Rib interference: The slots for the first and last internal bow ties directly face the internal ribs of the Floor End block, completely blocking their path.

I noticed a recent commit in the SKYLARK150 repository branch titled “Fixes to End blocks” and wanted to put this on the core dev team’s radar to see if this specific bow tie clash is already being addressed.

(I’ve attached CAD screenshots showing the clash below)

Thanks in advance!

Thanks for this @Marc - we’re taking a look and will get back to you shortly.

Hi @Marc welcome to the community :waving_hand:

It’s a good spot, but there is actually a reason for this. Because the END blocks has to work for both horizontal and vertical connections, the vertical bowties (to connect to the wall blocks) are installed before the top panels of the END beam are fitted in. The top panels should be left off until all wall blocks and bowties are installed, and then they slot in, hence the half-depth (9mm) tabs under the walls to make this easier.

Hope that makes sense?

Hi @Clayton,

Thanks so much for the detailed explanation!

I had considered that sequence when looking at the top panels, but seeing the fully assembled 3D model made me double-check whether that was the intended workflow. I’ll follow that assembly order.

One quick follow-up: looking at the image you shared, I noticed the wall corner and the floor end blocks show only two tabs on that section instead of three, which eliminates any rib interference. Is this updated tab configuration planned to be rolled out to the main repository soon?

Best,
