Identical aesthetic than double shear mods.

3.2mm drill bit (or good alignment and drilling skills)
2.5mm drill bit

BOM:
4 M3x26mm SHCS (i used 30mm like on double shear for plus/max. Max length is 52mm)
Recommended print settings:
Layer height: ≤ 0.2mm
Print orientation: as imported
Supports: Not required
Recommended materials:
PETG
ABS/ASA
