You'll need M3 bolts, heat inserts and laser cut handle you can bend in vices. Lobes of the handle lock into the bolt base slots. Works with pre-compressed K26. Laser cut the handle from steel - 2 mm survives indefinitely but for thinner plate metal you can prime placing index and middle finger on the handle lobes to keep the assemble centered while priming.
The author remixed this model.
A little bolt base remix to sink in a metal bolt handle working reliably for heavy prime configs.
