This is still a work in progress, will post updates as available.

Street light for slot car tracks. Mounts to my guard rail system. Could be mounted directly to wood if a spot is cut out for the wires. I am using 3 SMD LEDS wired in series for the light with a 91 ohm resistor on a 12 volt power supply.

Street light pole revision 1 is a cone 14mm on the bottom and 12mm on the top. This pole is 155mm tall.
Street light arm revision 1 is 8mm diameter.
Light housing revision 1 has 8mm hole for the arm.

Street light pole revision 2 is a cone 10mm on the bottom and 8mm on the top. This pole is 155mm tall.
Street light arm revision2 is 6mm diameter.
light housing revision 2 has 6mm hole for arm

Both revision are the same height. I personally think revision 2 looks better, more to scale.

Street light pole revision 3 is a cone 10mm on the bottom and 8mm on the top. This pole is 175mm tall, 20mm taller than rev 2 to accommodate the top brace of the arm.
Street light arm revision 3 is 6mm diameter and longer to better reach the track from the shoulder with a 4mm top brace.
Revision 3 uses light housing revision 2 


If you you have any questions or suggestions please let me know. If you make this please post it! I would love to see it.

Enjoy,
Kevin

**There is a newer version of guard rail system, v2.0. https://www.thingiverse.com/thing:4650422**

Except for the pieces that mount to straight sections, everything is designed to be mounted on shoulder pieces. If there is interest, I will add for mounting direct to the corners. Otherwise I will add as I need them for my track.

These can be pre-assembled except for the guard rail holder and installed in one piece. Once in place, the guard rail holder can be installed which pins the assembly to the track piece. If you have any questions or comments please feel free to ask. I try to get back to everyone in a timely fashion.

Things to be added:

1/3 straight
direct attachment to corners
inside corners
pit lane and transitions
Fencing for above guard rail in corners.

If you have any other ideas please let me know. If you make this please post it! I would love to see it.

Enjoy,

Carrera track guard rail system V 1.1

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:3867460.

My BLtouch died and I didn't feel like spending 45.00 for another one. I started searching Thingiverse and found Compact Opto Servo Probe by atsnailpace and really liked his design. The optical end-stop that I had was different than his so I decided to do a remix around his design. Since I was designing my own I decided to go with a smaller servo and a sewing needle for the actuator pin. The probe test pdf shows the results of 100 probe test and is a screen print from octoprint.

The endstop that I had was from amazon:
https://www.amazon.com/gp/product/B07MFT8NWJ/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1
The connector on the endstop had to be moved to the back of the board to be able to use it.

The servo was from Micro Center:
https://www.microcenter.com/product/508336/small-plastic-analog-servo

Post processing is a little bit of hole clean up. Used a #64 drill bit to ream the hole for the pin guide and a #63 for the pin holder-flag. to get the pin holder-flag to trigger the end-stop I used aluminum tape for sealing duct-work. As designed it takes about .5 to 1mm to trigger. it actually looks like nothing moves. 

I am using Klipper firmware for my printer so if you need help getting it going with klipper I should be able to help. I am not extremely familiar with marlin but will help if I can.

As always if you have any questions please ask, If you make it please post it, I would love to see it.

A good friend of mine that I race with regularly on my track mentioned to me if he had a couple hundred dollars to spare he would like to get a slot car dyno. (He knew exactly what he was doing by saying that to me, planting the seed!) I figured this would be handy to have for the modification I am doing on Carrera 1/24 car to allow adjusting the gear ratios.  After some research to see if I could get software for a dyno, I came across Simpledyno software. It is no longer supported but work perfectly for my needs and it is free. In the program you can enter the information about what will be on the dyno and it calculates the weight of the roller for the inertia dyno to be accurate.

Please let me know what you think! I am still working on refining the dyno and I am open to suggestions. If you have any questions please ask. If you make this please post it! I would love to see it.

Enjoy,
Kevin

1/24 - 1/32 slot car dyno

I have a bunch of 1/32 cars with no case and wanted a way of organizing them. The magnets are 10mm dia and hold the cars to the stand

1-4-2020 It has come to my attention that some of the cars that I have require a different magnet spacing to stay on the base. The following car have special bases.

30290 LAFerrari
30665 C6 Corvette
30618 Audi R18 TDI

If I find more I will add them.

Happy Racing,
Kevin

1/32 Stackable slot car stand

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:4083430.

I needed something to organize my 1/24 slot cars without boxes so designed this. Except being bigger this is the same basic design as the 1/32 stand. This is a 2 piece design because my printer is only 200mm x 200mm. The hole in the rear piece is 2.5mm so it can be tapped for a 3 mm screw. I used a M3 x 6mm to put the 2 halfs together. This also uses to same uprights as the 1/32 stand. Magnets are 10mm discs.

Enjoy and happy racing,

Kevin

This is a refinement of my original design, https://www.thingiverse.com/thing:3693712 . After using the original design for over a year I have found and corrected the issues I didn't like. This is a redesign of the original and is not compatible with the original design. So unfortunately the parts are not interchangeable.

To make a 1-30 corner use the 1-60 left and 1-60 right. 
To make a 1-60 corner use the 1-60 left, two 1-60 center sections, and 1-60 right.

Everything else should be pretty self explanatory.

If there is another location you would like to see the guardrail for please let me know.

If you have any questions please ask, otherwise enjoy! If you print it please share it!

Carrera guardrail system v2.0 shoulder mount

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:4074134.

Was looking for something to push with a car to be able to polish up the rails. Couldn't find anything so decided to make one. I am using 3M red metal finishing pad to polish the rails with 2 10mm diameter magnets to hold it down. There are two 2.5mm holes behind the magnets If you want to thread them to remove the magnets. Have any questions please let me know. Happy racing!

This car has a couple thousand laps on it and the front axle bushings were worn out. I figured before I ordered a new carrera axle I would try to make a axle carrier that could use bearings instead of bushings. I had some 1/8" bearings and a 1/8" axle in the spare parts bin to work with. Let me know what you think. If you make this please post it! I would love to see it.

I designed this to easily hook up a Arduino to the track power. The latest update to Bruce Yingling software, HSSRMS, allows using a Arduino to make the lane change button a call button to pause the race.Click the link below for more information.

 I hot glued this plug to a straight shoulder and ran the wire to a 3 pin dupont connector. I used 3 pin to keep from being able to reverse the polarity. The 3 pin connector is mounted in the outer track pin hole with the plug holder as seen in the pictures. Now when I install the shoulder it plugs into the power port on the adapter unit 30360. This also works on the CU power ports as well.

If you found this useful, please donate what you think it is worth to my paypal.me. Help cover the time of design.
Thanks, Enjoy!

I didn't have the room on my track for a shoulder around the pits. I didn't like the gap between the straight shoulder and the pit transition. So I designed a piece to make it look more complete. I will be adding adding a guard rail piece to my guard rail system for this and the pit lanes soon. I am considering painting this flat black and painting the red and white to match the existing shoulders. If I do I will post a picture. 

This part is 2 pieces because my print bed isn't large enough to print it whole.(I really need a larger printer!) It is held together with a Carrera red snap clip. If you have any comments or questions please ask. If you make this please post it! I would love to see it.

Enjoy,
Kevin

This is a ball bearing, hall effect, filament runout sensor. I am using a o-ring for the spring to close the switch if the filament runs out. The sensor triggers low (ground) when there is no filament in the sensor. The led is on if there is no filament in the sensor. This will work on either 5v or 3.3v. The led is slightly dimmer if used on a 3.3 volt system.
There are 3 different bodies for this sensor
<ul>
<li>One with built in stops for the ptfe tube.</li>
<li>Without stops for the ptfe tubing. (Custom cut the tube around the bearings)</li>
<li>One for use with ptfe tube locks.</li>,/p>
</ul>
If you have any questions or suggestions please let me know.

Hall Effect Filament Runout Sensor

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:4768760.

This is a remote filament feeder using a nema 17 stepper motor 3d printed gears and o-rings to grab the filament. There are 2 different bodies for this design.
<ul>
<li>4mm hole for pushing in and holding PTFE tubing.</li>
<li>5.7mm hole for screwing in PTFE tubing locks.</li>
</ul>
I designed this for a project I am working on and though others might find it useful.
If you have any questions or comments please let me know.
