About this 3D model

This is a pen refill gasket for Dragon Pen use. (Original author: wuguigui ) It is compatible with Zebra JF or Pilot LP3RF refill. Some domestic pen refills, such as the M&G G5, can also be used, but the length is about 1mm shorter. Therefore, I have made this gasket, which can allow inexpensive domestic pen refills to be used normally. This method looks more elegant than padding paper or stuffing Bambu poo. It has two versions: with an outer edge and without an outer edge: The outer edge version is very sturdy, but the pen refill with a thicker wall cannot be installed (approximately within 0.7mm). The without outer edge version is prone to detachment, but most pen refills can be used. Please select as needed. If the PEI board cannot be stick , please apply glue or turn on Brim .
