Centauri Carbon 7.5 mm Đệm Tấm

This spacer helps reinforce the edges of the panel for mounting hinges or providing extra room for an internal spool holder.

Recommend knurled heat-set inserts with this spacer unless you select the M3 nut version. If you have never done heat-set inserts before, you will need the following to get started:

• Soldering Iron - I use the Yihua 939D+
• Heat-set Insert Tool/Tips - This set is compatible with the 939D+
• Threaded Inserts, like this Brass Threaded Inserts Assortment Kit

If you don't want a more expensive DC soldering iron similar to the Yihua mentioned above, and want an all-inclusive and inexpensive way to get started, this kit will work just fine.

There are heat-set presses to help guide threaded inserts into your print. They typically include tips and the soldering iron, like the ones mentioned above. These are nice to have, but a luxury I have yet to invest in.

If you choose the M3 nut version instead of the heat-set insert version, the model was designed around nuts from a kit like this one: M3 Screws Assortment. The nuts from the manufacturer in the link fit tightly and don't fall out. Yet they can be pushed out by threading a screw partially and pushing out firmly.
