On carpets with higher pile the stock wheels and also the other tires I designed have not enough grip and causing wheelspin so.
So I designed a special profile for this carpet which will have much more grip there than the other profiles. A test was successful.
On hard floor these tires will produce a bit more noise than the stock wheels.

Edit 2020/12/19: Inspired by the remix by [jlcornwell](https://www.thingiverse.com/thing:3347822) which needs support to can be printed I simply scaled my model down to 50% in height and print it twice. Mounted both parts shifted by a half tooth on the wheel the robot runs more smoothly on hard floors now. See last photo.

To guide my wild vine branches along the railing of my balcony I made some clamps to be snapped over the balconies rail with enough space to guide the branches without squishing them. 
Unfortunately I'm not able to make this customizable. 
The inner size of the clamp is 76,5mm wide and 35,5mm height.

Because I didn't find a helper to measure the mismatch of the second toolheads offset direct, I made my own.
It doesn't look spectacular but helped me to exactly adjust the offset settings in my slicer program after only one print test.

The handlebar mount provided with a well known GoPro-Clone (left part) is designed for a handlebar with 22mm diameter. No chance to fit it to a 32mm handlebar.
With the uploaded part (mounted in the first picture) the holder now can be mounted on a 32mm handlebar.

Edit 2017/08/07: V2 with additional fillets for higher long term stability added

Because the original rear wheels of Neato and VR100 are very hard they make a big noise on tiled floor crossing the gaps between the tiles.
If you print the attached file with white TPE and replace the hard wheels with the new ones, you will not hear this terrible rumble anymore.
The rotation of the robot around its middle axis will not be affected by these softer wheels even on deep-pile carpet.

Recommended print settings:
Extruder temperature: 220°C
Print bed temperature: 80°C
Print speed: 20mm/s

Use at least four layers for top and bottom and four perimeter shells!

Estimated print time per part: 0:30h
Material per part: ca. 3g

To enhance my K40 lasercutter I used three Omron SSR found in my shack:

To be able to mount them fixed and isolated into the device I designed an extremely simple case. The four M3-screws at the corners can be used to only fix the cover or to mount the case when screwing through a wall inside the device. 
The PCB snaps to the stands and will be fixed by the cover.

The original rubber sleeves of the handle rods for the VELUX roller shutter become brittle over time and breaks out.
The part provided here can replace these sleeves 1:1.

All found models of brackets for FIashForge Dreamer for 3mm glass plates did not fit on my device.
Because the print bed of the Dreamer is wider than the 230mmx150mm glass plates ( http://tinyurl.com/he4vune ) the plates were not fixed safe on the bed and shifted around. The most of the found brackets were also too high.

So I made my own based on the idea of ADesigns: http://www.thingiverse.com/thing:965872

Because the size difference of the plate to the print bed is higher in the depth than in the wide the brackets must be asymmetric.
The wider side (with the skewed corner) comes on the longer side of the bed (X-direction), the side without skew comes on the shorter side (Y-direction).
As to see in the photo now the brackets fit perfect for the plate.

Because the original print plate of the FIashForge Dreamer is an additional thermal resistance between the heat bed an the glass plate I removed it to decrease the temperature difference between measured (and controlled) temperature of the heat bed and the real temperature of the glass plate.
But now the original brackets were a little bit too high sometimes causing a collision between the nozzles and the brackets.
So I reduced the height of the brackets to let them fit again.

Inspired by the adjustable Z-bed by brianvanh I wanted to have one which can be adjusted motorized controlled by the upgraded smoothieboard in the cutter.
The realized bed can move its surface up to 30mm below the lasers focus.
Beside the printed parts and some different M2 and M3 bolts and nuts there are the following parts necessary:
- 4 x quadratic aluminum profile 15mm x 15mm x 2mm length 300mm
- 4 x quadratic aluminum profile 15mm x 15mm x 2mm length 150mm
- 1 x NEMA17 stepper motor 17HS4401
- 4 x GT2 20 teeth timing pulley aluminum bore 8mm
- 1 x GT2 20 teeth timing pulley aluminum bore 5mm
- 3 x GT2 16 teeth idler aluminum bore 3mm
- 1 x GT2 timing belt closed loop 6mm x 1140mm
- 3 x M8 threaded rods 67mm
- 1 x M8 threaded rod 85mm for handle (if wished, otherwise 67mm too)
- 6 x M8 nuts (4 x if no handle is wished)
- 4 x 608 ball bearings 8mm x 22mm x 7mm
- 2 x micro switches 105126SPGJL5375
- 1 piece of stretched metal (better a honeycomb plate) 220mm x 360mm made of steel
- 8 x neodyme magnets round 15mm x 5mm

The function of the finished bed is to see on youtube: https://youtu.be/CRq5Kx4GHnM

Mechanical digital clock with network time acquisition

I made this incredible simple but genius clock by shiura and found, that the parts have to be glued or welded together. Because I'm not a friend of nondetachable connections I tried to make the respective parts new from scratch to be able to mount them by simply joining them together.
The ESP32 was a bit oversized for this simple job in my mind. So I designed mount positions for an ESP8266 and the stepper amplifier in the base to fix the PCB safe in the case. You see here only the modified parts. The original number cylinders you can get from the source by shiura.
The firmware had to be adapted to the ESP8266 and ist available on [github](https://github.com/xSnowHeadx/MinimalClock). To prevent the mess with timezones and daylight saving I used the [WTA-API](https://worldtimeapi.org) instead of the NTP-service. So your timezone can be figured out from your public IP and no firmware modification is neccessary for all timezones.

Edit 2021/08/31: added option "PRE_MOVE" in firmware for earlier start of motion to reach target position just in time

Edit 2021/10/18: added slots in the bases to hold the snap-in-tongues of the [additional base-bottoms by Art_Lieberman](https://www.thingiverse.com/thing:4987737)

Improved the resolution of 8x8 pixles by using the better Sensor MLX90640 with 32x24 pixels. Modified TC_front and TC_sensor-plate for use with both sensor types and added a fitting decoration for the new sensor.
The firmware and schematics for the new sensor are available on [github](https://github.com/xSnowHeadx/thermo-cam_V3) too.

Based on an inexpensive kit from China, a Geiger counter for monitoring the radioactive ambient radiation was created.
