3D CAD Files

Here are some 3D design files mostly relevant to the PDP-8. These should mostly be printable with common 3D printing services like Shapeways, etc. Because .stl is no longer the prefered format, be advised that all of the STL files are now in mm, not inches.

Use the link in the page footer to let me know if there are issues with these files.

In no particular order:

An 11/70 style switch lever. STL file (Metric) Sketchup file Print profile I don't actually have a machine, but they seem to operate like the originals.	This is a clip meant to mount the later revision 8/A Programmer's panel. STL file (Metric) Sketchup file Print profile (You'll need one each with left and right divots drilled and tapped.) Experimental: Although I think it's close, it hasn't been printed and tested.
This is a model of the bar that positions and protects the 8/E/F/M lamps. STL file (Metric) Sketchup file It also isolates the individual light sources. Experimental: While I think it's close, it hasn't been printed and proven yet.	A full size model of the PDP-8/I bezel. STL file (Metric) Sketchup file (I don't have a printer big enough to print it.)
A PDP-8/I style switch lever. STL file (Metric) Sketchup file Print profile These are also used for peripherals (TU56, TU10, etc).	Card guide for the BA11-M chassis. STL file (Metric) Sketchup file This variation was contributed by Alex (ajacocks at VCForum).
A set of parts for an attempt at an HP pen holder. STL file (Metric) Sketchup file	A set of parts for an attempt at pen holder for short felt pens. STL file (Metric) Sketchup file
A set of parts for an another attempt at a pen holder. STL file (Metric) Sketchup file	A 3D model of a space pen. STL file (Metric) Sketchup file
The knurled knob for the Calcomp plotter. STL file (Metric) Sketchup file	A card guide for an 8/A chassis. STL file (Metric) Sketchup file Print profile I think these may also be suitable for 11/34 and similar machines. Status: Finished. These are flimsy like the originals, but seem to work.
A new card guide for an 8/A chassis. STL file (Metric) Sketchup file Print profile I think these may also be suitable for 11/34 and similar machines.	A pair of card guides for an 8/A chassis. STL file (Metric) Sketchup file I think these may also be suitable for 11/34 and similar machines. Status: Finished. These are flimsy like the originals, but seem to work.
A flip-chip module handle. STL file (Metric) Sketchup file Print profile	A flip-chip module handle with label inserts. Print profile
An experimental H-850 card extender. STL file (Metric) Sketchup file Print profile I haven't had any of these printed yet.	A carrier for a 14 pin DIP. STL file (Metric) Sketchup file Print profile Status: Finished.
A carrier for a 16 pin DIP. STL file (Metric) Sketchup file Print profile Status: Finished.	An experimental Nova 3 switch lever. STL file (Metric) Sketchup file These still have some fit issues.
This is a box designed to house the RasPi 0W and the Flip-Chip tester. STL file (Metric) Sketchup file Print profile It is finished and works well.	This is a guide frame to center the flip-chip module in the tester's socket. STL file (Metric) Sketchup file This is for use with the slightly over-wide sockets. It works OK, though I'm not enterely happy with the over-wide sockets or this work-around.
This is a guide frame to center the flip-chip module in the tester's socket. STL file (Metric) Sketchup file This is for use with the slightly over-wide sockets. This version is upside down so that the support prints on the outside. It works OK, though I'm not enterely happy with the over-wide sockets or this work-around.	This is the frame for a 6u rack cover panel. STL file (Metric) Sketchup file Experimental.
This is the frame for a 6u rack cover panel. STL file (Metric) Sketchup file It's broken into a two piece kit to make it easier to print, but it is still too big. Experimental.	A more complex/expensive box for 8 inch floppies. Print profile
A simple box for 8 inch floppies. Print profile	An attempt at a switch handle mold (left side). STL file (Metric) Sketchup file
An attempt at a switch handle mold (right side). STL file (Metric) Sketchup file	The LED guide block for the Life board from Spare Time Gizmos. STL file (Metric) Sketchup file I have not printed this.
An attempt at the rack logo panel for an 8/I. STL file (Metric) Print profile	A rack the size of a connector block (2x4). STL file (Metric) Sketchup file Print profile
A small rack, suitable for one double height moddule, STL file (Metric) Sketchup file Print profile or two single height modules.	A rack suitable for storing up to four quad height modules. STL file (Metric) Sketchup file Print profile
A small rack, suitable for up to eight single height modules. STL file (Metric) Sketchup file Print profile	The computer end of a DEC current loop cable. STL file (Metric) Sketchup file Print profile (This end has the female sockets/pins inside.) I have printed these sucessfully.
The terminal end of a DEC current loop cable. STL file (Metric) Sketchup file (This end has the male pins inside.) I have printed these sucessfully.	A model of the bulb cover for the RK05 drives. STL file (Metric) Sketchup file
This is the tubing coupler inside an RK05. STL file (Metric) Sketchup file This was made of (and should be printed in) some rubbery substance. Experimental.	An example of the RK05 replacement drive label. Print profile
An RL02 "drive 0" indicator. STL file (Metric) Sketchup file Print the indicators in something translucent (nylon), as they will have lights behind them.	An RL02 "drive 1" indicator. STL file (Metric) Sketchup file
An RL02 "drive 2" indicator. STL file (Metric) Sketchup file	An RL02 "drive 3" indicator. STL file (Metric) Sketchup file I also have drawings for "4" through "7", if you've got an RK06/RK07.
An RK06/RK07 "drive 4" indicator. STL file (Metric) Sketchup file	An RK06/RK07 "drive 5" indicator. STL file (Metric) Sketchup file
An RK06/RK07 "drive 6" indicator. STL file (Metric) Sketchup file	An RK06/RK07 "drive 7" indicator. STL file (Metric) Sketchup file
A replacement foot for the VT01 (Tektronix 611). STL file (Metric) Print profile	The base for Doug's drill jig, for switch handle repairs. STL file (Metric)
The top for Doug's drill jig, for switch handle repairs. STL file (Metric) Print profile	A mold for a switch handle. STL file (Metric) Sketchup file
A mold for 16 switch handles (enough for a color batch). STL file (Metric) Sketchup file	A mold for a pair of switch handles. STL file (Metric) Sketchup file
The switch toggle used on most models of PDP-8. STL file (Metric) Sketchup file Print profile This is based on some earlier work by phooky.	A print job for 16 switch handles (a color batch). STL file (Metric) Sketchup file
Thin trim panel bracket with barbs. STL file (Metric) Sketchup file Use thick or thin depending on whether there's equipment behind the trim panel or not.	Thin trim panel bracket with screws and sturdier but gentler engagement. STL file (Metric) Sketchup file Print profile
A single rack bracket, oriented for durability of the printed part. STL file (Metric) Sketchup file Print profile	Thin trim panel bracket with screw holes. STL file (Metric) Sketchup file
Thick trim panel bracket with barbs. STL file (Metric) Sketchup file Print profile	A pair of rack brackets, oriented for durability of the printed part. STL file (Metric) Sketchup file Print profile
The classic XX2247 keyswitch. STL file (Metric) Sketchup file Print profile You're better off getting these duplicated at your local locksmith.
