3 x 1U and 2 x 1.25U "Ctrl" Silicone Keycap Molds

Create your own custom keycaps with this silicone mould set featuring three 1U (standard single-key) cavities and two 1.25U Ctrl-size cavities. Perfect for mechanical keyboard enthusiasts who want to craft bespoke resin keycaps at home.

The two-piece mould works best with UV-curable resin for clean, detailed results — two-part resin can be messier and sensitive to temperature and humidity. Once cured and removed from the mould, keycaps fit any Cherry MX-compatible switch.

Key Features

  • 3× 1U Cavities – Standard single-key size (bottom row, R1 profile)
  • 2× 1.25U Ctrl Cavities – Modifier key size for Ctrl, Alt, and similar keys
  • Cherry MX Compatible – Moulded keycaps fit all MX-style switches
  • Two-Piece Mould Design – Silicone construction for easy demoulding and repeated use

Ideal For

  • Custom mechanical keyboard builds
  • Resin casting and keycap crafting
  • Artisan keycap makers

Package Contents

  • 1× Two-piece silicone keycap mould (3× 1U + 2× 1.25U cavities)
Tip: UV-curable resin is recommended for best results. A UV lamp is required for curing but produces cleaner, more reliable keycaps than two-part resin.
