#3dPrinting: Durst M605 Reproadapter

The repro adapter mounted on the column of the M605 with the camera attached.
The repro adapter mounted on the column of the M605 with the camera attached.
For my Durst M605 colour enlarger I needed an adapter to attach a camera to the column and thus be able to use the enlarger as a very accurate repro stand. Unfortunately, the existing solution for the M670 from oet does not fit, and I also find it quite difficult to print. So I constructed a new adapter from scratch that uses their camera mount, so that if you own both enlargers - which is quite pointless but nevertheless possible - you can continue to use them. The adapter itself follows simple shapes and can be printed without supports. For the attachment to the boom you need a M8x30mm hexagon screw and the star knob from samyp.

Download my adapter at thingiverse.

For the mounting of the adapter and the camera holder you still need

1x M8x30mm hex bolt and a M8 hex nut
2x M6 x25 nuts and countersunk screw
1x M4 x 30 nut and screw
1x 1/4" screw

Ikea Hacks. High Heels for Ikea PS: Stilt One

Picture shows an Ikea PS Cabinet
The cabinet was raised 45 milimeters.
Our IKEA PS cabinet needed higher legs. Therefore, I have constructed a few extensions that make the cabinet 5 centimeters higher. The extensions simply slide into the square tubes after removing the caps. To increase stability, you can secure the extensions with M5 bolts and nuts, so that nothing is guaranteed to wobble. I recommend drilling the necessary holes at the back of the legs. To facilitate the marking of the hole, I quickly made a drilling template: This instead of an extension push into the tube, through the 2 holes on the template mark the places where they must be drilled, or best of all immediately set a drill mark with a center punch.

I recommend the use of PETG. or ABS, PLA might be too brittle. Best 25% infill. Print the parts lying flat on the printing plate to increase stability and to avoid predetermined breaking points, which might occur when printing upright. Set supports for the areas of the extension that will be inserted into the square tubes.

If something sticks: A few hearty blows with a hammer never hurt anyone ;-)

#3dPrinting: Pegboard Toolholder for different Sets of Screwdrivers

I use Küpper workshop furniture in my workshop. The equipment from them is, let's say "in the better DIY quality" category. (For a cabinet in industrial quality you often have to pay as much money as for half a workshop equipment from Küpper). Also from Küpper are the tool walls, which have their own "standard" regarding the hole spacing for the individual tool holders.

However: For my Felo ergonic screwdrivers as well as for Wiha screwdrivers with wooden handle or also the (planned) Wiha VDE screwdrivers there are only "universally" suitable, i.e. unsuitable holders. Therefore, I have constructed a few quick'n'dirty suitable holders on the fly.

#3dPrinting: Watchmaker's Bezel Lifter

 Disassembled bezel and bezel lifter with inserts
Disassembled bezel and bezel lifter with inserts
I needed a bezel lifter for the revision of my Kemmner Mechanik Turtle watch. Since the commercially available are simply too expensive for me, I make myself a homage to corresponding models on my lathe. As a preliminary step, I have designed the part as a 3D print to see if everything fits as I need it. Of course, the model must also work, but I can not say anything about the durability in a professional environment.

The tool is designed so that also inserts in other diameters can be made, I have added inserts for 44mm, 42mm and 40mm bezels.

Application: The two half-shells are connected with M4x30mm cylinder head screws, and the appropriate inserts are placed in the groove inside. The whole thing is then slipped over the bezel of the watch, so that the angled edge of the insert lies in the gap between the watch case and bezel. Now tighten the two screws alternately and with feeling. The clamping will lift the bezel off.

CAUTION: Do not use brute force. Even if the lifter grips the bezel, it is possible that it will be bent by brute force! Also remember that there is usually a spring underneath and a spring or rubber ring directly in the bezel ring, and that these tend to get loose. If the bezel is stuck with the lifter and won't lift off on its own, a slight turn clockwise or counterclockwise will usually help.

The bezel can be easily reassembled by pressing it back onto the case according to the mark on the inlay. This works best by hand.

DIY: Rose Indexer

Ein nützliches Tool, das ich in unseren Breiten noch nicht gesehen habe ist der "Rose Indexer". Damit kann man Rundmaterial, das während oder nach der Bearbeitung in einem definierten Winkel im Schraubstock gedreht werden soll, schnell versetzen. Tubalcain hatte das kürzlich in dem Video hier verwendet, auf der Suche nach dem Tool musste ich dann angesichts des Preises schon schlucken, obwohl ich Kummer gewöhnt bin. Selber aus Alu anfertigen sollte relativ problemlos möglich sein, bedeutet allerdings auch einen gewissen Aufwand. Also erstmal nach einem Prototypen schauen und zufällig fündig geworden: Rose Index - Indexing fixture ist inzwischen ein "dauerhaftes Provisorium" bei mir, die Genauigkeit ist für den gedachten Zweck völlig ok, ich habe das in ABS gedruckt, ggf. können die Anschlagflächen natürlich bearbeitet werden. Wenn so ein Werkzeug ständig im Gebrauch ist, sollte das natürlich stabil gefertigt sein.

Warum nicht einen Teilapparat oder Collet Block nehmen? Die werden ja nicht überflüssig durch den Rose Indexer, der Anwendungszweck ist einfach ein anderer, zudem lässt sich so auch unrundes Material spannen. :pfeif:

Vielleicht kann das ja der eine oder die andere brauchen. Hier ein Foto eines Versuchsaufbaus:

Take back the night - wir nehmen uns die Nacht zurück!

Foto: © neukoellnbild via Umbruch Bildarchiv
Am 30.04.21 wollen wir unter dem Motto TAKE BACK THE NIGHT gemeinsam als FLINTAs auf die Straße und uns diese nehmen. Die Nächte sind weiterhin oft eine Bedrohung für viele, insbesondere für uns Frauen, Lesben, Trans- und Interpersonen. Dies soll nicht so bleiben, sie sollen uns gehören und wir werden sie uns nehmen. Lasst uns unsere Wut sichtbar machen und uns die Nacht zurücknehmen! (Aufruf zur Demo)

Es war eine kraftvolle, wütende und emotionale Demo, die sich am 30.04.2021 angelehnt an die feministische Tradition vom Spreewaldplatz in Kreuzberg auf den Weg nach Friedrichshain machte. Rund 2000-3000 Frauen, Lesben, inter, nichtbinäre und trans Personen demonstrierten gegen alltägliche patriarchale Gewalt auf der Strasse, im Club oder in häuslichen Beziehungen. Für die Anerkennung von sogenannter Sorgearbeit, gegen die Ausbeutung unter Coronabedingungen, in Solidarität mit mutigen Feministinnen in Polen, Großbritannien, Mexiko und anderswo.

„Wir wollen uns von den Bullen, die oft genug nicht nur wegschauen, sondern selbst frauen- und transfeindliche Gewalt ausüben und uns die Liebig34 genommen haben, nichts gefallen lassen.“ So war bereits im Aufruf für eine offensive Demonstration mobilisiert worden. Auch wenn die Polizei mehrmals die Demo wegen mangelnder Abstandsregelungen stoppte, liess sie sich nicht aufhalten und zog laut mit viel Rauch, Pyro und Feuerwerk bis kurz vor den Endpunkt in Friedrichshain, wo sie sich selbst auflöste.

#3dPrinting: Riser for Clothes horse

On bad days, my robot hoover tries to overcome the legs of the clothes horse and sometimes fails. Then shit happened again.

The widespread solutions with "wings" or clothespins as an obstacle did not convince me, so I simply designed a few risers that can be clamped to the feet of the clothes horse. The only function is to raise the legs by 1 centimeter, which is enough to trigger the bumper on the vacuum cleaner.

The riser is designed for a pipe thickness of 16 millimeters and should also be able to be clipped onto thicker pipes. Thinner pipes are also possible, then simply wrap a little tape around the pipe a few times to give the riser a hold. Gaffa will do the job, or you can use a few drops of hot glue.

You can download the necessary files from my thingiverse or prusa3d account.

#3dPrinting: Bracket for Xiaomi MI Vacuum Cleaner Mini

A pre-production model
As some of you know, I hate nothing more than housework. Therefore, everything that is possible is automated here. For example vacuum cleaning. A Roborock S5Max is working on the floors in our lumber room, but what about the crumbs from the cake on the tablecloth? This is the job of the recently released MI Vacuum Mini Cleaner, an accu-powered mini cyclone vacuum cleaner that does its job well, but unfortunately comes without a wall bracket.

So I just broke a simple and hopefully functional design from the fence, which is based on the same of the Xiaomi designers. I say so now ... ;-)

However, here it is for your convenient use. I printed it with matte white Extrudr PLA NX2, which is beautiful and goes well with the matte finish of the cleaner. However, here it is for your convenient use. I printed it with matte white Extrudr PLA NX2, which is beautiful and goes well with the matte finish of the nipple. You don't need to use supports when printing, or you may have problems removing it from the cable duct in the floor. You can use the part with the two openings on the back that are intended for attaching the holder to the wall with two screws. By the way, the distance between the necessary holes would be 40mm.

Have fun with printing and always good 1st layer adhesion ;-)
