Here's the problem I had slicing this model for FDM printing. Resin may be the best option.

Switch Lever Prototype Files

These files may be difficult to print with an FDM printer - a nozzle 0.3 mm or smaller is recommended, as the curved body of the design is extremely thin. It is probably better to consider printing these in resin instead.

Note: the switches available on AliExpress already have the lever and it is only necessary to print your own if you want period-correct colouring.

These Rear Card Handles attach to the 6 rear circuit boards (2 handles per board). Thus, 12 are required for a full set.

Hi. Welcome to the Educ-8 Microcomputer Forum.
Primarily this is a place where I hope to collate information about the EDUC-8 Microcomputer build I'm embarking on. Elsewhere in the forum I will be adding content, links, images, and whatever information I can gather on my modern build of this machine. I'm just assembling - all the hard work has been done by others. But I hope this forum can bring all the disparate information together so those who follow have an easier time making sense of it all.
Please feel free to join, modify, and contribute.
