Description: Printing:
- Use a flexible filament. Avoid PLA as it will break quickly. It has been printed with "Nylon" filament and it works well.
- The precision has to be quite important. In PRUSA MK 3 printer, it has been printed in a very fine setting.
- As the base is a bit elevated near protrusions (which imho is not needed, but it was in original), a layer of supports should be added at the ends of the base. Especially with the "Nylon" filament which doesn't want to stick to the bed.
- At least in my case, the printer generated a lot of "fuzz" around the protruding parts. This should be carefully cut out.
- PRECISION: To operate and reatin properly, the angle between the base and the edge of protruding parts should be taken into account. This angle is intentional.
- I decided not to include the cuts in the base to increase sticking to the bed. And they are too fine for current printer. Add them if you want.

Description:
This is a front sticker for BASIS 108 computer. It is flat, with protruding "BASIS 108" text and a logo. This has been made from photos and measured from the recess for sticker in my unit. The font used is called "Sportscenter" and looks like this is the font originally used. It was printed in PLA, Prusa Mk3 printer, 0.07mm accuracy, finished with ironing of the topmost layer, silvery default filament.
After printing, I coated it with dark-brown (unfortunately too light) lacquer and then the front side has been removed with sandpaper to obtain brighter letters.

Description:
A key for Siemens PC/X, PC/D, PG685 or similar keyboards. If a key does not fit and protrudes, it may be needed to remove a bit of material from bottom part of a keycap.

Description:
Measured from Quadra 800, printed and successfully used in Workgroup Server 8150.
This is a bit hard to print as it's quite complex model. Button plungers must move freely and be "hanging" only on springing parts. Thus, the springing parts should not be printed the way that stress, normal during operation, could cause delamination. The only alignment in which squeezing springs would not cause delamination is to print the shape on the side, which in advance makes supports so hard to remove that you will rip the part anyway during removing of supports.
So, I printed it on the "bottom", means big flat part with two holes to the bottom. This way it went skewed, but printed well and it operates. To strengthen springs which may delaminate, it may be needed to weld (using e.g. a hot soldering iron) a short piece of metal wire (from paperclip) in parallel to the vertical part of springs when it turns to the button front.

Description:
A digit (small) key for Flying Fish mechanical calculator. Preferably print without supports as supoprt may block the hole for metal part and this is not easy to remove. There is 8mm of hole inside, so if it's too high, remove material from the bottom.
