4 x 1U and 1 x 2U "Esc" Silicone Keycap Molds

4 x 1U and 1 x 2U "Esc" Silicone Keycap Molds

Discontinued

A two-piece silicone mould set for casting your own custom keycaps. Includes four 1U (R1 profile, function-key size) and one 2U (Esc / Enter / Backspace size) cavities, compatible with Cherry MX-style key switches.

UV-curable resin is recommended for the best results — it cures quickly and cleanly with a UV lamp, avoiding the temperature and humidity sensitivity of two-part resin. Once cured, the keycaps pop out of the flexible silicone mould and fit directly onto any Cherry MX-compatible switch. The 2U keycap can be used for Esc, Enter, Backspace, or other double-width keys depending on your keyboard layout.

Key Features

  • 5 Keycap Cavities – 4× 1U (R1 profile) and 1× 2U (double-width)
  • Cherry MX Compatible – Cast keycaps fit standard MX-style stems
  • Two-Piece Mould – Top and bottom pieces for clean, detailed castings
  • Flexible Silicone – Easy demoulding of cured keycaps

Ideal For

  • Custom mechanical keyboard builds
  • Artisan keycap crafting
  • Resin casting and UV-cure projects

Package Contents

  • 1× Two-piece silicone keycap mould (4× 1U + 1× 2U cavities)
Tip: UV-curable resin gives the cleanest results. Watch this tutorial for a step-by-step guide to casting custom keycaps. Also available: 1.25U Tab mould and 1.5U Caps Lock mould.
