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. Directory STL file (Metric) 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. Directory STL file (Metric) 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. Directory STL file (Metric) 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. Directory STL file (Metric) (I don't have a printer big enough to print it.)
A PDP-8/I style switch lever. Directory STL file (Metric) Print profile These are also used for peripherals (TU56, TU10, etc).	Card guide for the BA11-M chassis. Directory STL file (Metric) This variation was contributed by Alex (ajacocks at VCForum).
A set of parts for an attempt at an HP pen holder. Directory STL file (Metric)	A set of parts for an attempt at pen holder for short felt pens. Directory STL file (Metric)
A set of parts for an another attempt at a pen holder. Directory STL file (Metric)	A 3D model of a space pen. Directory STL file (Metric)
The knurled knob for the Calcomp plotter. Directory STL file (Metric)	A card guide for an 8/A chassis. Directory STL file (Metric) 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. Directory STL file (Metric) 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. Directory STL file (Metric) 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. Directory STL file (Metric) Print profile	A flip-chip module handle with label inserts. Directory OpenSCAD file Print profile
An experimental H-850 card extender. Directory STL file (Metric) Print profile I haven't had any of these printed yet.	A carrier for a 14 pin DIP. Directory STL file (Metric) Print profile Status: Finished.
A carrier for a 16 pin DIP. Directory STL file (Metric) Print profile Status: Finished.	An experimental Nova 3 switch lever. Directory STL file (Metric) These still have some fit issues.
This is a box designed to house the RasPi 0W and the Flip-Chip tester. Directory STL file (Metric) Print profile It is finished and works well.	This is a guide frame to center the flip-chip module in the tester's socket. Directory STL file (Metric) 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. Directory STL file (Metric) 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. Directory STL file (Metric) Experimental.
This is the frame for a 6u rack cover panel. Directory STL file (Metric) 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. Directory OpenSCAD file Print profile
A simple box for 8 inch floppies. Directory OpenSCAD file Print profile	An attempt at a switch handle mold (left side). Directory STL file (Metric)
An attempt at a switch handle mold (right side). Directory STL file (Metric)	The LED guide block for the Life board from Spare Time Gizmos. Directory STL file (Metric) I have not printed this.
An attempt at the rack logo panel for an 8/I. Directory OpenSCAD file STL file (Metric) Print profile	A rack the size of a connector block (2x4). Directory STL file (Metric) Print profile
A small rack, suitable for one double height moddule, Directory STL file (Metric) Print profile or two single height modules.	Doug's quite nice module storage stuff. Directory STL file (Metric) Print profile These are what I store most of my modules in now. Print the bits that you need for your storage solution.
A rack suitable for storing up to four quad height modules. Directory STL file (Metric) Print profile	A small rack, suitable for up to eight single height modules. Directory STL file (Metric) Print profile
The computer end of a DEC current loop cable. Directory STL file (Metric) Print profile (This end has the female sockets/pins inside.) I have printed these sucessfully.	The terminal end of a DEC current loop cable. Directory STL file (Metric) (This end has the male pins inside.) I have printed these sucessfully.
A model of the bulb cover for the RK05 drives. Directory STL file (Metric)	This is the tubing coupler inside an RK05. Directory STL file (Metric) This was made of (and should be printed in) some rubbery substance. Experimental.
An example of the RK05 replacement drive label. Directory OpenSCAD file Print profile	An RL02 "drive 0" indicator. Directory STL file (Metric) Print the indicators in something translucent (nylon), as they will have lights behind them.
An RL02 "drive 1" indicator. Directory STL file (Metric)	An RL02 "drive 2" indicator. Directory STL file (Metric)
An RL02 "drive 3" indicator. Directory STL file (Metric) I also have drawings for "4" through "7", if you've got an RK06/RK07.	An RK06/RK07 "drive 4" indicator. Directory STL file (Metric)
An RK06/RK07 "drive 5" indicator. Directory STL file (Metric)	An RK06/RK07 "drive 6" indicator. Directory STL file (Metric)
An RK06/RK07 "drive 7" indicator. Directory STL file (Metric)	A replacement foot for the VT01 (Tektronix 611). Directory OpenSCAD file STL file (Metric) Print profile
The base for Doug's drill jig, for switch handle repairs. Directory STL file (Metric)	The top for Doug's drill jig, for switch handle repairs. Directory STL file (Metric) Print profile
A mold for a switch handle. Directory STL file (Metric)	A mold for 16 switch handles (enough for a color batch). Directory STL file (Metric)
A mold for a pair of switch handles. Directory STL file (Metric)	The switch toggle used on most models of PDP-8. Directory STL file (Metric) Print profile This is based on some earlier work by phooky.
A print job for 16 switch handles (a color batch). Directory STL file (Metric)	Thin trim panel bracket with barbs. Directory STL file (Metric) 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. Directory STL file (Metric) Print profile	A single rack bracket, oriented for durability of the printed part. Directory STL file (Metric) Print profile
Thin trim panel bracket with screw holes. Directory STL file (Metric)	Thick trim panel bracket with barbs. Directory STL file (Metric) Print profile
A pair of rack brackets, oriented for durability of the printed part. Directory STL file (Metric) Print profile	The classic XX2247 keyswitch. Directory STL file (Metric) Print profile You're better off getting these duplicated at your local locksmith.
