The filament spool roller on FLSUN SR 3d-printer (their base-model) is nothing more than a simple metal tray against which the spool will loudly overcome the friction and skid around.

During one cold evening I designed and printed a replacement roller using supplies I already had in my workshop.

Our family car has a roll-up trunk cover which protects its contents from prying eyes. The sliding mechanism relies on two pins, protruding from brackets in the cover, to slide forward and backward within the trunk.

Recently one of the pins broke and I replaced it with a 3d printed part.

I’m making available my CWmouse iambic paddle for purchase.

I designed it for my own use as a lightweight, hand-held, portable paddle based on micro-switches. Use of these switches gives it a crisp action not unlike that of a mouse button or a mechanical keyboard.

I’m so happy with the final result, that I decided sell them.

For more information, high resolution pictures and to order one, visit cwmouse.com.

I returned back to Internet’s roots, to a personal web server.

Back to the basics from the world of centralized, controlled and censored platforms.

Decision

Instead of running Mastodon, or any of alternative ActivityPub servers, I elected to stand up (again) my own personal web site. Requirements are: control, simplicity and ability to integrate with ActivityPub and other future open protocols.
